all someone had to tell me was that I couldn't do it. Careful what you say to a self made engineer from the trailer park . . . music: Skorned Psychosis
Edit: I did actually end up manufacturing the carb cheater and am currently on order number 2,018 or so - seriously ... Can be purchased here: carbcheater.myshopify.com/ to put a definitive end to all the "this or that wont work" comments - everything in one video that address all the arguments. Am I promoting the idea of putting a mower carb on a vehicle? no - but dang what a fun science experiment! Now the Carb Cheater has raised a lot of questions - if I did go through the effort to sell that tech as a kit, would there be any interest? Would be a lot of work on my part.
The first thought I had (aero-engineer) was the small carb was running a higher velocity at the same mass flow of air/fuel for the power the engine is making. That could create turbulence itself due to boundary layer effects. Your 90 degree turns also would be effective for mixing the fuel and air. I think your theory is correct on atomization of the fuel. Apparently you found a sweet spot in all of this and created something amazingly good at efficient operation. Nice job!
A tunnel ram enhances the mixing of air and fuel..a mower carb and bends chokes the engine, starves it of air..if it didn't he wouldn't need to create a vacuum leak.
@@brettjasonhead3740 no man, it is more like the opposite of choke. It's not less air volume than the carb at wide open. It's more air volume. The "vacuum leak" is to regulate the flow rate of the fuel jet.
@@mikedonovan9573 all the OEMs have figured out how to make a high mpg engine, but greed and politics has kept it out of consumer hands. We don't need catalytic convertors and all the complexity. A clean burning, efficient engine lasts forever because if all the fuel is being utilized there is no carbon fouling.
@@hoost3056 lets hope someone gets into some form of government position that realizes this and takes down emissions stuff and catalytic converter requirements. then we can have high mile v8s. if that person happens to be u, u have my vote, guaranteed
@@hoost3056 this is true and I definitely support your thinking, the government had issues with clean burning engines because they burned hot enough to make NOx emmisions thus the colder burning, less gas efficient and dirtier cat required modern cars. I am willing to admit that I know nothing of the dangers of either as I am not an environmental expert and I personally don't care too much. (I'd love it if global warming made ohio like south Carolina and got rid of Cleveland and toledo in the process!) Just a fun fact I learned from a video on why hydrogen engines never took off, and why mid 90s hondas are so good om gas.
LOVED YOUR LAWNMOWER CARB ON V8 VIDEO !! I've done a similar fuel conversion on a nice vintage 86 Chevy 4x4 van that came with a factory installed camping interior. I did the 4x4 conversion & engine swap a few years ago, my wife & I used this rig to tow our RV & assess the backcountry. It's running a 383 stroker, auto trans & a gear vender. I purposely kept the running gear on the van old school with no computer as I'm somewhat electrically challenged. I conducted several years of research prior to delving into these projects & to avoid melting down the newly built stroker motor. With a 4-barrel carb this rolling breadbox gets 10 mpg on a good day with a tailwind. I first converted it first to run on hydrogen but output was not sufficient. Note; Prior to experimentation & avoid engine meltdown issues I installed Manifold Temp. & Air/Fuel ratio gauges. I ultimately converted the van to run very well on a gasoline vapor unit I designed that includes a float valve setup installed in bottom of the unit.. I'm currently running a chinese knock-off of 54 Chevy single barrel carb on the van. Bet a lawnmower carb like yours would work equally well if it was used in conjunction with a vacuum advance like you built. Most don't realize that Henry Ford patented a working gasoline/kerosene vapor unit back in the teens. I was fortunate to observe one of Ford's factory units work on a local truck & was provided with the plans. Only issue is that gasoline vapor freezes same as propane, I believe the solution is to introduce more exhaust heat from the manifold but got stopped a couple years ago due to health issues. My goal was to try & exceed 100 mpg running vapor & distribute plans for free to those interested. This goal would not likely be well received by our taxation & energy moguls.🤣 *The vacuum tuning unit you built is very ingenious, wish you were closer to Idaho to consult & incorporate on my project. I'm now 81 with health issues so unfortunately the van may end up with another like minded mad scientist. I would welcome your input. Chuck T. Kuna, Idaho
@@tims7219 Apologies' for the late reply Tim. My vapor setup works very well on my 383 stroker & produces excellent EGT & air/fuel ratio results on the gages. Only issue is the vapor freezes up under higher rpms. I introduced some heat via copper tubing to the exhaust manifold but was not enough to resolve the freezing. Unfortunately age '82' & health has put a halt to completion so will be selling the 4x4 van. Hopefully find a new owner who will add enough additional manifold/exhaust heat to perfect the operation.
Too cool. I remember a guy in the 70s, during the gas crisis then, being able to get 28 mpg with a V8. It's rather disappointing that my current truck only gets 14 mpg. I know the manufacturers can do better. You did it in your garage! You are amazing. Thank you for the great video.
I say sell it as a product, There’s a market for it, especially in nowadays fuel prices reaching a higher price every day. Why not? Make 30 units, sell them for a fair price that you and the customer walk away happy, maybe apply for a patent? I say why not? It’s an extra stream of revenue to secure a brighter future! You sir, are American ingenuity at its finest!
A patent only gives you option to sue an infringer at your own expense. Unless backed by a major commercial company you will not be able to afford that. Process totally skewed against small individuals. Better to just be known as the main guy in the field, the original inventor (something YT nowadays allows you to do, as you are doing right now) and just be the first, the best and most well-known.
@@XenonJohnD This isn't even a new concept, nor new stuff, just a 3D printed adapter anyone can make... try to sue that and you'll be the morning news laugh of the day...
I don't understand why you would think that this wouldn't work. When I was a boy, the neighboring farm had an old international dump truck with a 600 cubic inch inline 6 in it. The intake manifold and exhaust manifold were mated together, and it had a tiny 1 barrel carb on it. It was decent on gas, but it had to completely warm up.
I'm 74 yrs old and you just blew me away ! Had visions of the Pogue Carburettor and the Long Range Desert Group right off the bat. Not just well...but extremely well done sir ! The World needs more people like you !
You the man brother I'm 58 I've been working on cars all my life and I'll tell you what I never thought of that but I seen Ian Russell build a 3-wheeler chopper with Honda 6 cylinder engine and he put a regular I think I'm Otis a little carburetor something like that on there and made his own intakes all intake tubes into one little car and man that thing was beautiful ran perfect so you know I can see the way you put it out there on your board and that thing you made it kind of makes all sense I mean wow but like that other guy said boys going to be after you or want you to take it off look at that guy who made an engine that ran on water he disappears and sold it all the plans so fat back and bacon grease buddy you the man piece
@@WilliamNordeste I also had a CRX 87' and my dad moved the cam forward one tooth and it went from 48mpg to 52mpg and pulled so hard it would torque steer! Ahhh I should have never sold it.
I loved the comment about "over carbing" your engine. I had a 1985 F250 with a 351M. I thought I was hot sh1t as a teenager and slapped a 750 holley on top thinking I was going to get awesome power. I never did get it tuned right. I even switched brands to an Edlebrock 750. The thing still always ran like crap. A guy I worked with, built and raced drag cars and stock cars and informed me my carb was way too much for the truck. he took a 600 edelbrock right out of the box, slapped it on and the thing ran like a raped ape. in a half hour my guy took everything I thought I knew and tossed it right out the window 😂
@My Pronoun is WTF yes each engine i can be wildly different. The reason the 351 Modified didn't do well with a big carb is because of the cam. It was designed for a lot of low rpm torque, which made it a poor candidate for a big cfm carb. Basically it wasn't capable of using all the air available with the 750 and all the drivablity went away. To note, I also had a 302, that ran great with a 750. But it wasn't stock like the 351m.
"he took a 600 edelbrock right out of the box , slapped it on and the thing ran like a raped ape " 😭😭😭 I'm dying here my man , what a legendary saying I love it bawhahahaha brilliant 💪😜😂😭
I don't really care for the edelbrock carbs too much... They work good and all, but a proper sized and set up Holley will always make more power (just a better design).
First of all... I am not a mechanic or a tinkerer even close to anything to your level. I'm just a necessity fixer, cause I grew up poor and things need to run. However, what you're doing I wouldnt' call impossible becoming reality. What you're doing is the most, real to life, hot rodder thing ever... but in reverse. Unlike all the 70's and 80's EPA shit... you're accomplishing some of it while keeping the sound of the car, the fun of the car, and useability of the car at a maximum considering. You're true to spirit it seems. Good job my dude, great work
The IAC unit was brilliant. That's the advantage point. This shows that it IS possible to make a Carb unit compliant inexpensively and be made completely functional. Fantastic job!
That carb cheater of yours is great. I'm not surprised at all that the thing ran on a mower carb because I've messed with them enough, but that cheater of yours really puts the whole thing together. I'm really impressed with your understanding of electronics, software, and mechanics. Pretty uncommon to find someone who's as capable with a keyboard as they are with a screwdriver. I really need to get my feet wet with the 3d printing and app stuff, would really open up some doors for me on my hobbies.
@@CoincidenceTheorist I will when the time is right. Life's a bit busy right now so I'm holding off on buying a 3d printer. When I finally have time to mess with a 3D printer, there will be newer/better offerings on the market.
@Steven Reese I got an Anycubic Kobra Plus in the new year. It has been a hassle free printer so far short of having to input custom printer parameters into the slicing software.
This is Automotive Genius at it's finest and shiniest example, bar none. In history, men have had their lives ruined and their inventions to save fuel cost have been destroyed. Ridiculous or not, we all, as end user consumers, have been denied those ingenious benefits. I think this is a wonderful "FU" to the greed of mankind. It does not matter where you come from, I appreciate your tenacity to prove the point AND for keeping your channel OG.
He ain’t the first and neither was the guy that did the basically the same thing in the 70’s that turned up dead and all his information on how he did it was taken and kept under wrap.
Love this! You know people have forgotten that for MANY years single barrel carbs ruled absolute. Granted they were designed for automotive use and not a lawnmower, but the point is, they were very capable carburetors. My '62 Chevy II had a single barrel Ball & Ball that would roast the tires without hesitation, the added velocity of the charge was key. Also to note, I had a 1976 Monte Carlo with a 350cid engine that originally came with the large 2 Barrel which I swapped out for a Quadrajet. My mileage jumped from around 21 to 27 because of the much smaller primary throttle bores (as long as I kept my foot out of the throttle. The move to larger carbs was needed for the demand for power which quite frankly sealed the fate of the efficient single barrels because the general public started demanding power over efficiency.
Needless to say I am impressed. You need to market this! As a motorhead that enjoys restoring vintage vehicles, this would make those older classics less expensive to drive on a day-to-day basis. I would buy this set-up no questions asked.
Keep in mind that this was only highway driving in a straight line in Iowa. Traffic in Iowa I would imagine must be sparse and the state is mostly flat. Modern cars can already adjust for fuel trim and timing advance and an ungodly amount of catalytic converters.
@@eaglewarrior8707 And most newer cars are not getting 40 MPG and flat, sparse highway either. Especially larger engines. Heck, most smaller engines are not getting that.
@@eaglewarrior8707 the results are the same with other underpowered vehicles, they are tested in similar ways, unless asked otherwise. It is the poor and stupit game of the government manipulators of money and the stolen corrupt venerated fortress of god's they stole and have claimed to have overthrown god. they are shit.
@@yunusertas you can easily increase your MPGs with a 4 barrel as well. Take the same concept he has here, adjust it and apply it to the 4 barrel. I don’t see how or why it shouldn’t work. Maybe not 40 mpgs but you can definitely get better than out of the factory.
@@Jeff-qq4zotrue, but the two setups might not provide gas milage prepositional to their prospective horsepowers (A 300hp car could get 15mpg while a 150hp car, with more efficient combustion, might make closer to 40mpg)
The general idea behind the spread bore (a.k.a Quadrajet) is to run on as small of a carb as possible until you need the extra air. Carbs work best when they have high flow
I just happened to stumble upon this series at the start. I don't even know how it popped up in my view list but you had me interested right from reading the title of your first posting. I have been an automotive tech for over 30 years and I am quite impressed with your level of knowledge for your age. You effortlessly are able to explain all the science and engineering behind this project. I remember a long time ago hanging out in the garage with my buddies and discussing conspiracy theories about big oil companies buying up patented fuel economy devices just to keep selling fossil fuels. I really think your onto something here. I can't wait to see what happens with the 4 barrel. Please keep us posted on that.
I’m very excited for the 4 barrel test - will it give insane mpg? Doubt it - but there’s no harm in afr optimizing a carb to get the best fuel economy that that sized carb can provide
You do realise all of this has been invented tried and tested before now , this dude is just showing how it's done from his own levels of ability , the oil tycoons have killed people like him over and over to silence them so they can sell more fossil fuels , one thing I do agree with you on though he has a great head on young shoulders
@@ThunderHead289 heres a challange i have for you. roadkill style trip across america with the lawnmower carb. some spare tools beer or soda(idk if you drink or not). and some custom merch. let others follow you real time making the trip.
@@ThunderHead289 Funny thing is De Ja Vu I was working on a snapper lawn mower with a Briggs and Stratton engine and thecarb bowl was gunned after putting it back together I noticed somewhere I didn’t screw the bolts on all the way where a plastic piece feeds fuel air to engine and I said wow this is really atomized no fuel injection can get gas to be vaporized to smoke 💨 and I said this is what someone needs to put on a car and try maybe a bigger version of the same carb but oh yes it explained that the guy that made the carb for a car to run 60 mpg is real it’s probably a light car though. And it’s not far fetched carbs we can work on fuel injection and every new element seems to make the car worse to work on for average folks so they buy a new car
@@jonnykielbasa I have a built 351W with a Holley Demon four barrel I’m going to get rid of the Demon and put a cute little two barrel in it. At today’s gas prices 4 mpg doesn’t work very well
@@foxmaine3921 I don’t think you’re understanding why they’re using a tiny carb on a v8 or 4 cyl. Itbs or ic setups aren’t know for being efficient just strong
I think you did well...in 1982 I worked for Honda we had ordered a few Civics that had a little tiny one inch or less Throttle plate on them and they were apparently good for 62 miles per gallon ..fun fact .. That air in a smaller intake will travel faster than air in a bigger one..plus if you want to increase air in a smaller pipe just mount a small egg into the intake with a variable height slider ..it will pull in more air..old german Tech
I knew an old guy who told me about old carborators getting 60 mpg then that old tech was bought and hidden from public use. This video makes me believe him. Most excellent video, thanks man
Yeah I'm almost certain we had the knowhow to have far more efficient vehicles long ago but to keep the industry neverending advancements get put out in a planned order. That and planned obsolescence will keep us buying cars for many decades to come.
My 2018 GMC half ton crew cab 4x4 with the 5.3 gets 30 mpg on the hiway at 60 mph and has tons of power , I had a GM sprint with the 3 cyl many years ago that got 75 mpg on the hiway , the manufacturers have done a great job moving a lot of weight with the power that people want .
Well Done Champ. Your control device is so elegant. So impressed. Yes that smaller carb venturi allows for superior fuel atomisation but it's your wise management of stoichiometric ratio under differing engine loads that takes full advantage of the better gasification = it is simply beautiful. Probably superior to any MPFI for economy.
Loved the comment about coming from the trailer park-where you've been in life is never as important as where you are going. In life, we regret the things we do a lot less than the things we didn't-if you're unsure about how to improve your life, action beats inaction every single time and you miss 100% of the shots you don't take in life. I build automated processes in my company and am a tool and die maker by trade and started on the shop floor. Everyone in this country has that opportunity no matter how humble our beginnings-you just have to want it.
If there EVER was someone who DESERVED a "liked and subscribed", it is certainly you, my friend!! Exceptional effort! Amazing Video!! It does my 66 y/o heart proud to see that there are youngsters of your caliber out there today.. Well done my man! This video will be on my mind for quite some time, I'm sure!!
Honestly this is a brilliant idea , Proves that their is alot of potential for gas engines to get better gas mileage. And it does not take crazy complex tech / Direct injection. Dont need 300Hp just to go get grocery's lol lol Im sure some will argue with that. Well done sir. Well done!
The problem is the market i.e us drives what the automakers put out. Your average mid level family vehicle is 270+hp. You have to actually search to get less power more efficiency. If the majority of ppl wanted 40+mpg we'd have it. But the majority want 40+mpg out of a v8 suv with all the extras I'd also like to add the main reason he thinks this works is the atomization of the fuel. That's what direct injection does. On top of being atomized, when something that high pressure is released it provides a cooling effect. I belive it was audi who had 13.5 to 1 compression on 87 octane with direct injection.
@@beavistechrock Difference with direct injection is fuel air mixture is less mixed than with turbulence of this lawn mower carb. arrangement. Naturally , modulated direct injection allows for much higher compression ratio on low octane fuel but how does that pan out in terms of economy? I have a notion that a combination of a lean carb. mixture, fuel/air cheater AND direct injection things could really get interesting. I experimented with direct admission propane into a 4 cylinder 40HP diesel and found it would put out about 60 HP and no smoke. One big company, and I fail to remember who tried a similar experiment with highway tractors but did not follow it up. \
You find the right formula on a slightly larger carburetor and 300 h.p. could still take you to the grocery store, i do worry though about lean burn ratio,
@richardbarber4444 from what I understand d.i allows higher compression. The higher the compression the more energy you can extract from the fuel. However, higher compression also equals more nox? Emissions. When you've got ceilings of cost and drivability I don't think we can get much more out of gas engines. For example on a new grand cherokee they are making everything they can out of plastics and aluminum. The hood is aluminum, the front subframe/cradle, the control arms and spindles as well. Thats saving anywhere from 250 to 500lbs vs the last generation. I believe going forward weight savings with partial plug in hybrids will be the rule of the day before we go full electric.
This is mind blowing. Obviously you have got a lot of mechanical and electro digital and drafting/engineering knowledge. Got to say I am extremely impressed. Very well done. Keep up the experiments and best wishes in the future.
You do know the eventual has to happen. A complete intake manifold replacement with 8 of those carbs stacked up like a Ferrari with a stack of Webers! I DARE you!
This is the kind of content I like, I'm always on the lookout for informative auto related material. Man, this project really goes the distance. More of the same gets my vote.
I’m so impressed with everything you’ve done with that lawnmower carburetor. I would totally pay to get this set up on my RV to lower the gas consumption.

As a 3D printing enthusiast (custom built my own 3D printer out of the parts of another), I would highly recommend you use a 0.5 (what I run) or a 0.6mm nozzle, with layer heights around half the nozzle size. High resolution for that type of part probably isn't super necessary to its function. Also, your part probably doesn't need to be as beefy as you made it, considering it's not running under any real pressures. Instead of making the base of it so thick, maybe add ribs instead. Slim it down, take a lot of the unnecessary material out, and save yourself some filament money! Great work man, your MPG result is pretty crazy.
I'd recommend layerHeights =< (nozzleDiameter/phi) for strength. I'd say go equal to that number for speed & strength. I like lineWidth = nozzleDiameter too. I agree, 0.6mm diameter is a great nozzle in terms of speed and detail. There's also an interesting recent video by CNC Kitchen that I'd seen which details the maximization of printing speed with respects to volumetric extrusion.. The title is "Easy Hotend Benchmark for FAST PRINTING Profiles" IMO that idea is revolutionary in the same sense of applying the small engine carb to the V8. If you set that up then you will save so much of your valuable time! ..especially if you want to mass produce kits.
@@Paint0nBrush when he closes the throttle the vacuum probably jumps up to around 29 or higher which puts atmospheric pressure on the outside trying to collapse the plastic intake, I say beefier the better especially under the hood with the heat.
I think it would definitely be worth your time to try commercializing the system. Try it out on your 1964, and your 390 V8 truck for more proof of concept. If you could get 25 MPG out of the truck... (I know it’s low geared)
@@shermanwest3168 what eauggg oohhh humm, I wouldn't know anything about that , All I know is never showed for his datsun tune up .... OK , I GOTA GOO !........LOL
That was cool, being a small engine man. Always knew that once a lawn mower engine went past design rpm levels it went fat, never gave it a thought of a vacuum leak to thin the mixture. We used to build racing mowers and really spin the motors on them. Ya know using twins and singles. Reworked ignitions to help with the response. Basically doing the same as you. Huh this video really scratched the old think lump. Thanks.
Dude! I've wanted to experiment with something like this for over a decade. Glad a fellow Iowan was the one to try it out. I've been looking at various carbed cars the past couple years, intent on getting back to my roots, and now I really want to try that setup on whichever I end up getting. I'm hoping for the 78 Buick Regal V8 if all goes well the next few weeks. I'm moving from Texas back to Cedar Falls soon, too, so I'd love to have someone as motor-nerd as I am to bounce ideas off of. Rock on man! 40mpg in a 78 Regal for daily driving and road-tripping is my main goal for the year.
This is the coolest stupid thing I've seen that worked soooo much better than expected, as it wasn't expected to even work. Great work on working out all the problems.
Great vid! All around impressive experiment, curious on the dyno numbers. The mpg's are worth what ever the power loss is, make a two carb system... lol. Keep up the good work, and yes sell the kit! Don't miss this opportunity, people will buy it, fuel isn't getting cheaper👍
Your grasp of the tech involved in what makes an engine run is very impressive. very well done young man. Yep I may just try this myself, I have an inline 6 with a two barrel on it and a pile of lawn mower carbs.
Carb conversions are my favorite. Me carburated my previously EFI Honda Civic for funsies. First version was a VW beetle carb. Second Version was the WEBER 32/36. I used a 1990 DPFI intake manifold and made adapter plates. I think my next project will be my vg30 on my Nissan hardbody. It is always nice to see someone who shares the same hobby.
I once heard a story from my Uncle who I cant imagine would lie, But in 1946 he bought a Chevy Sport sedan that got 60mpg. He took it back to the dealer and told the salesman what a awesome car and how it didnt use any fuel! He got the car back a few hours later and fuel mileage was 15mpg. Supposedly GM let a new experimental carb get out the door.
I feel like boomers all spread the same three nonsense stories. It's always "my uncle." I think Americans of a certain generation just love tall tales. Thr mystery csrb is a popular one. The other is how Cletus got free electricity by running coils under a power line and powered his whole house.
I think I was more impressed by your 3d printed parts and your vacuum control setup than the overall success of the test. I'm no expert in fluid dynamics, but it all made sense to me and why it was successful.
Great little series man! Love the content and your style. You seem like the guy I’d love to meet at car shows and swap meets and just talk car and motor stuff!
Fun build. I had a 72 4 door that I bought for $100. $25 at the junk yard replaced the fender/bumper and related junk. I drove it for about 2 months without an air filter and a connecting rod found it way out of the block. Good times.
I would definitely like to see this run on a slightly more definitive fuel measurement, put a gallon in a container and tie it in then drive it till it’s almost drained measure the remaining amount in the container and calculate mpg
@@colormesarge -- All the regulations and inspections do is try to ensure that a pump measures a fixed amount of fuel within an acceptable variance, not that it is consistent in when the nozzle thinks the tank is full... They want to ensure that if the pump is charging you for 5 gallons of fuel, you are actually *getting* 5 gallons of fuel. Nozzle shutoff is what can vary and makes his way of testing potentially inaccurate... A pump speed (gallons per minute delivered) can vary over time. If it is pumping at a slower rate, it will allow more fuel to get into the tank before the nozzle shutoff occurs... I've been able to get over a gallon of extra fuel in a car by pumping slow... I've also seen pumps that delivered fuel so fast that the nozzle would kick off when the tank was only half full...
The fuel climbs up the filler neck and shuts off the fuel. That's got to be accuracy within like 2 oz. Especially when it spills out on the second fill.
Great stuff man, ingenuity at its finest! I would love to see more detail on how you designed and built that idle air bypass to keep the AFR's around 14:1 though, and the app design. I'm good with all the mechanical and ignition stuff, but that APP and your FMB (fucking magic board) you built are beyond me.
I would treat that 41 mpg with a bit of skepticism and here's why. Your distance traveled was only 39 miles which is way too short to establish a reliable mpg number and secondly filling the tank at a service station gas pump won't reliably top off the tank with exactly the same volume of fuel each time. That can easily vary depending on the horizontal position of the car fore and aft and side to side at the time of fueling. I can see how that volume could vary by a pint, a quart or even a half gallon. With only a 39 mile drive that fuel volume difference can skew the mpg number quite a bit. Your theory of better gas vaporization sounds very plausible and increased mpg with that small carb to me is believable. What I would like to see if for you to do the same test and burn a much larger volume of gas over a greater distance. Enjoyed your video very much. Very educational stuff!
Your absolutely right about everything, I see a half gallon variable depending on the slight angle differences between stations. Every car is different too, mine gets less fuel with the front down hill. I will say in defence of the MPG number he got that his car with a 4 barrel carb might get 15mpg on a good day, so the setup he got is still a significant improvement even with that variable at the pump.
Hi Luke, I just have to thank you for the incredibly informative and helpful content you put out. Very impressive, you've helped countless numbers for sure. Please consider creating some type of Carb Cheater tech kit. You would again be helping countless numbers in a world where rising costs are pushing many to make some tough choices and find efficiencies wherever possible. With some of the highest food prices and gas here in Eastern Canada nearing $9.00 a gallon it's becoming quite a struggle for many, myself included. I would quite happily rip into my daily/work truck, an 88 F150 with an aod trans, remove the efi system and convert to a similar setup you've accomplished with the Maverick. The knowledge and understanding to put that setup together has proven to be quite valuable given the interest shown. I stand with them and would definitely invest in what you've created. Cheers from Canada

I was like most everyone else on the size of carbs needed, then I got my '73 Ford F-250 with an FE 360. It came with a 2 barrel, and I immediately thought like most everyone else that it'll need a 4 barrel. Then I found the math and found "360 ci x 4800 rpm divided by 3456 = 500 cfm". Question appeared then, how often will it be turning 4800 RPM? (hardly ever), it makes maximum horsepower @4000 RPM and maximum torque @ 2400 RPM. So a Holley 500 CFM 2 Barrel carb is more than I'd ever need. But increasing it's fuel mileage with that setup is definitely of interest to me, especially at these prices. Let's keep this going.
In theory, a vacuum seconday 500 cfm 4 barrel would be better. The primary side would be smaller, giving a much better signal and mix. This is why Quadrajets were popular. Very tiny primary and gigantic secondaries. Thermoquads as well, even if they do leak.
I like your era of music my brotha👍 I'm a huge Primus fan myself. Keep on doing what your doing and thank you very much for the awesome content my brother.
I bet that thing actually got 80 mpg. I'd like to see what that could do in a smaller, lighter, more aerodynamic car like a Prius with the battery removed for weight savings. You're a genius. You certainly know what youre doing. Keep fooling with this. Hope the oil companies don't scrag you like they did that young man with the S10 and the guy with the water car.
Hi. This was an interesting 1 hour+. Most lawnmower (carbs) I have tried work with e85. You could also try ethanol (blends), which produces a leaner mix. Blocking the radiator helps retain some of the heat of the engine, to get into efficient burn zone. You also noticed, the vacuum in the manifold is deeper. Thus, the initial pressure starting the compression stroke is lower than with a big carburetor. Therefore, your engine is running Atkinson-cycle. You noticed it yourself from a quieter exhaust note. With normal timing, there will not be knocking, because the initial cylinder pressure is lower. Thus, to get even better mileage and increased horsepower try advancing timing (even more with e85. Until the point of knocking). Also, lowering the head could give better efficiency, to be in par even with stock cylinder head pressures. If you do that, instead of 41mpg, you could probably do 50mpg .. MIB's helicopter heist 80mpg..
As a Brit with a Chevy K10, this is intriguing. Our fuel prices equate to $8.30 a gallon over here, so fuel economy is always a consideration. You've now got me thinking whether a V8 will run on an older SU type needle carb. I think you've definitely got an angle going on here. Keep it up!
My 98 K1500 is starting to give me trouble with all the electronics and bullshit. It’s looking awfully tempting to rip all the computer shit out and stick one of these puppies in here. The only thing that’s getting me is the varying loads, think I’ll tune it to run at 55 and just stick to country roads.
We have heard this about a carb. Gives 100 mpg the company buys the right etc. Etc. But here is proof there's something to it? We are being robbed my car manufacturer, and Big oil!!! Bastards!!!! Great stuff guy.
doing a awesome job on this, way back during bush and gas hitting 4.00 a gal i was fooling with hydrogen generators to increase gas mileage. managed to get a merc capri from 25mpg to 45 mpg. i would love to see you add a hydrogen generator to your lawn mower carb which would be pretty easy to do. i bet with the combo you would hit over 100mpg
I would be very interested in seeing a full pull with the lawnmower carb setup. Daily driver looks to work fantastic and mind you, I'm not looking for quarter mile figures, just curious as to how a full pull would be.
I had a 71 Maverick with the 200 6 cylinder in high school, I can appreciate the Coleman heater, it hardly defrosted the windows in our mild NC winters. But Coleman stoves were not propane in 1982, they were white gas, pressurized with a hand pump and hanging off the front of the stove by stamped steel drop-in tab retention. I remember camping in the Boy Scouts trying to scramble eggs, knocking the tank off the stove and having the vapor tube pissing fire across the campsite. Good times....really they were, life was so much simpler then. Edit: I like the comment "Careful what you say to a self made engineer from the trailer park . . .", after 34 years in the Acura/Honda repair business I'm working in manufacturing surrounded by engineering BAs, MAs and PHDs; great guys and gals, but they often can't see the obvious because they are collecting data points or trying to abide by the latest corporate 'objective'. They recently dismantled and scraped our trusty ultrasonic vapor de-greaser in the processing department for an aqueous parts cleaning solution to meet a perceived reduction of hazardous chemicals need; parts requiring sealant are failing because the manufacturing lubricants are not completely removed. We are now using combustible solvents in small heated ultrasonic cleaners at point of use; rather than the isolated, fire control system equipped process department. But I'm Just A Dumb Ass Mechanic.
