Rebuild An Edelbrock 4-Barrel AFB-style Performance Carburetor - Detroit Muscle S1, E5 

Years ago I was taught by an old dirt track racer how to rebuild a quadrajet and let me tell you what I can make a quadrajet out perform any carburetor on the market and the duo Jets as well

This is great, now more people will give me their quadrajet. Thanks guys!

Notice they didn’t focus camera on edelbrock carb sticker at the end. The cleaning solution ate it up. I wonder if they sell the stickers? It finishes off the rebuild 👍🏻

Thank you so much. When I was rebuilding my 59, El Camino. I spent an afternoon rebuilding the WCFB carburetor. I learned a lot. Then I rebuilt the 283 Chevy motor. It was so inspiring when I started it up and my dad adjusted the idle with his ear!!!! Yes, that is old-school hot rodding!!!! Great video and a great carburetor!!!! Thanks for sharing.

I put a Quadra jet and Delcotron alt. on my 1966 Mustang in 1973. Ran real good.

That Quadrajet brought back some memories. Remember my dad rebuilding one of those when i was a kid.

I remember rebuilding my 4 barrel on my 66 Plymouth, wife couldn't believe I could but it all back together. Back then rebuild kits were not expensive.

Thank you so much guys!! Helped me rebuild my first carb!

How to check a brass float, pour boiling water into a mason jar, use needle nose pliers to hold the float below the surface on the water in the jar, the hot water makes the air inside the float expand causing a stream of bubbles, if your going to soldier a hole closed and want to remove any fluid from inside the float, allow the float to reach room temperature, while holding the float with pliers making sure the hold you found is pointing down heat up the float with a heat gun, the heat expands the air in the float forcing and liquid out the hole, do not use and open flame, gas vapor inside the float can explode, i have done this many times with no problems.

When I was 15 in 80 in Houston my friend who was two years older than me had this 69 javelin. It had a lot of miles on it and it was a six cylinder.

Love my Saturdays!

Great video but at 16:40 it shows you placed the pump connector in a Z pattern rather than an S pattern which is backward. The Z pattern has the tendency to break the pump rod when pressed down hard. Dont know why I noticed it but thought I would share it with you and anyone else who are rebuilding their carb. My 500 cfm had that problem.

I got a 71’ AMX 390 3spd auto, out of a barn in 85’. I put a holley 650, electronic ignition, hooker headers, glass packs, nice mid-range crane cam. When it was tuned to perfection by my buddy Doc(you know who you are) it really ripped up the dirt roads and paved ones as well. I bought cheap rear tires because the car would melt’em off quickly. Thank you for reminding me about that great American car. Proud to own one.

What a great show. I always learn something valuable. I just finished my 1969 AMC AMX GO PACK WITH EVERY AVAILABLE OPTION 390 . I took 8 months to do the paint and body work . The 93 octane gas went bad and ruined the mechanical fuel pump and the brand new 750 double pumper carb. Holy smoke. I had no idea gas was so horrible today. The gas smell in carb was disgusting. Finding a pro to rebuild was a challenge. It cost 125 to find an old school shop in clearwater fl to rebuild it. Keep up the great show. By the way, I had the dip stick tube break off at the block, what a pain. I figured out how to remove and replace with 390 still in. Great show.

Great tutorial, thanks ! 👍

You did it congrats on one million gentlemen

Thank you, great video

This would of been great if you would of showed the pride of General Motors..the Quadrajet

One of my life long friends had an AMX in high school in the late 70s. 390 car, and it was bone stock. He made a lot of GMs and Fords eat his dust. He still has it today, and has restored it to a concourse condition jewel.

Freiburger’s favorite punching bag. The thermoquad!!!

Thanks, great tutorial, my carb is running like new

**I MUST HAVE REBUILT MY Q'JETS 100+ TIMES = EASY!!! GREAT CARBS = SO WERE MY CARTER AFB'S = LOVED BOTH!!!** **ALWAYS USED THE AFB's ON LARGER DISPLACEMENT ENGINES**

THANK YOU, SUMMIT RACING!!!!

can you guys please do a holley rebuild episode aswell. these videos are so entertaining.

67👍's up PN thanks again for taking us all along with you

Miss these guys and the old show.

Start by vacuuming that card off not compressed air. Spend a lil time with a stiff brush and a shop vac. If you ever want to clean your engine & bay, start with a stiff nylon brush and a vac. Makes a difference.

Those AMC cars are awesome looking little cars.... I remember seeing several of the red, White and blue one's..... never drove one light weight for sure,,,My 1964 Chevy ll' was 2640 stock form...but 350 LT1 and Muncie 4 speed 12 bolt Positive.... I can relate.....to what the guy was saying.....

Except for 4165 wich is speadbore.

Great vid!!!!!!!!!!!!! 👍👍👍👍

I would have rebuilt the Q-Jet and put the Carter-Edelbrock in the Dumpster

Carburetor rebuilding is a lost art. Most people just pull out their credit card and buy a new one. I've been rebuilding since the 60s and started on lawnmower carburetors! Rebuilt my first AFB on my 65 Dart 273 HP.

I also replace the intake for a E-street performer , better than the stock one

Just put a Crowler mechanical superstock Cam in a 68 AMX 390 go pack 4 speed car , the motor was stroked to 440 cubic inches. They have oiling problems with higher lift say .550 or so camshafts because of the AMC lifter design with a small oil groove compared to Chevy. I went back and researched what AMC used for Superstock Cam spec's and found out that they were cam's under .500 lift. .460-490 approximately. You can use less lift and add duration up to around 240 degrees @.050 lift and still have power brakes in A 4 speed car. You can't just throw a big Cam over .500 lift in Any AMX and expect it to last long because it won't. You can rig up the oil system with extra hoses and other oiling crap under the intake manifold if you insist on running a huge roller camshaft in A AMC block. But if you drive any real miles The solid roller Cams and bearing type rocker arms are not very street friendly to begin with due to excessive spring pressure and Are designed for track only car's. I've seen failure in a month on street car's and sometimes just a few days. I like the 401 AMC engine with early screw in stud stock head's and A reasonable lift camshaft in it. They made a 360 AMC engine also that was a pretty good screamer when built correctly. The down side of building anything AMC is the price of everything performance is getting really expensive and impossible to get. Management was The Biggest AMC problem stemming from four going bankrupt companies that never really got it together. My Grampa had A 1959 Rambler American Station Wagon with a flathead and stick shift. I don't consider any AMX to be Any kind of threat to Any of The Corvette's considering the better looks of The 68 to 72 Corvette's. Even a cheap big block mustang can be fast, but it will never have anything near the style of The base model Corvette. Not to mention The SBC reliability and ease of performance. And The 427 and 454 Rats rule the tracks around the world on race days ! . Chevrolet used Carter carbs in the early days on dual and single 4 V applications before The Holley 4 V carburetor's became available. Simplicity and durability is what makes Carter carbs very user friendly. For Serious Racing The 4500 Series Holley Dominator is The King of Carbs .Q Jet's are a joke for most people but I have seen a few that worked extremely well At the Drag strip but only a select few. Even I was impressed with how well they worked and how fast they went. Little engines but extremely fast with A Q Jet , The exceptions to usual Carb rules. Any vacuum secondary Carb is going to be less responsive than a mechanical secondary Carb. But it is possible to get a vacuum secondary Carb working pretty good especially Holley with A trick kit installed properly. I was watching this video because I am getting ready to set up two Carter 600's on A 355 Chevy engine in A street / mostly drag car. I believe that The Little Chevy 355 Small Block engine is going to love having 2 time's 600 CFM or the total of 1200 CFM on top end. And with the Carter carbs design I think that it will be street friendly also. It's not always just the part's but it's the total combination of the part's that makes the difference. Just getting the best parts you can is not going to be A good combination. I've seen many people who have made that decision only to regret it in the end. I used to straighten out messes like that for people when I was young and I usually had to change At least half of what they bought and start their build over Again. I learned that the hard way from the speed merchant who would sell me 3 or four of the wrong camshafts before he sold me the right one ! No names will be given ! , But that's the way it was back in the 1970's and without understanding And reading Peterson's book of Automotive Math it was a trusting the advice of the speed merchant and the other racer's who usually just played follow the leaders and copy them. Now we have the internet and you tube and A little bit more information. But remember that they are speed merchants and conscience has very little or nothing to do with most of them. They are trying to sell You As much crap as they can get you to buy. Listen to the old racer's advice and his experience and don't think he is Old school and not with it because he has most likely already forgotten much more than you will ever know ! . The basics of performance are always the same and experience and An open minded student is The person who hears from The teacher. It takes natural born talent to get a really good reaction time from The Christmas tree at the track but it takes racing knowledge to be A real winner and to have a very constant car that can run the same number over and over Again into the winners circle. A burnout cost's you some money but winning a money race can buy you New slicks and another day of racing. I'm not A 1/8 mile racer, I race 1/4 mile only and I don't like re entry buybacks because it is dishonesty during the eliminations. Put it on the trailer and go home if you can't win in the first round, your stinking bribery and 1/8 mile makes me sick ! . I noticed that Television NHRA event's do not allow buybacks ! Hypocrisy of the track owner's, The corporate sponsors and The NHRA organization allowing buybacks to be hidden from the general public. The buybacks Are going on during The points racing season that Are not being Televised. Why does NHRA and track owner's and corporate sponsors hide the corruption that is going on from the general public ? . Just think about it ? , You beat him in the first round of eliminations and you have eliminated him but he bribes or buybacks his way back into the race and then he could end up beating you in the final round of eliminations even though you already eliminated him in the first round of eliminations. He shouldn't even be there after you eliminated him in the first round of eliminations. Write a letter or email to The US Attorney General's office complaining about The buybacks and NHRA complacency on the issue of buybacks and the bribery ! . I have complained over and over Again to NHRA and track owner's and corporate sponsors and no one is willing to do anything about The buybacks and the bribery going on during points racing and eliminations. Not to mention The discrimination against 1/4 mile racer's and the much smaller winning amounts being paid for racing 1/4 mile. You race twice as far as 1/8 mile and get paid less for being true to the sport of 1/4 mile Drag Racing. That's why Tag's Are going on many of The 1/4 mile race cars of yesterday ! . They don't have any tracks left that Are being honest during eliminations and that Are running serious 1/4 mile money races anymore . The fans are not coming anymore either because 1/8 mile is boring to watch. There's more people coming for Street 1/4 mile nights then At Any other times with no winnings at all, it really shouldn't be like that At The Drag Strips. Eliminations have become meaningless today because of buybacks. Street night 1/4 mile is basically just paying for test and tune. But you can go just to race your friends car if you want to. That's the up side of 1/4 mile street night's. But you can do that on the street also and take a slim chance of actually being caught. The people who built serious 1/4 mile drag racing car's and who refused to change and rebuild their cars for 1/8 mile racing have been sold down the river by The track owner's, By NHRA and By their corporate sponsors. Before NHRA and Buybacks and Corruption took over the sport of Drag Racing it was Always 1/4 mile drag racing.

The Q-jet is the better carburetor. The Edlebrock is a repop if the Carter AFB. If you’re going for a square bore carb, a Holley, or one it’s clones, is a much better choice.

Wow by the time i buy the bucket of carb clean & all those parts then needing air tools & air compressor which i dont have in my garage it would be less to just buy a rebuilt carb all ready to go..but i liked watching the video very good..info...

If you feel that Q-jets are complex, move up to some Webers!

I can make a Quadajet sing ,,, I liked the Cadillac and Big block version larger float bowls,,,jet and metering rod changes are my well kept secret....but anywho those Edelbrock dudes are way more simple and produce smooth and easy adjustable power....way less parts for sure..😎 Thanks great video...

Quadrajets are complicated? What are you talking about Q-jets are one of the easiest carbs to work on

I have a used Edelbrock carburetor the on a rebuilt 350 engine and the engine runs good but the carb only runs with the choke closed and will not run when its open and I checked for air leaks and there is none is there anyone that can help me... rebuild it or get another one?

Never thought of the quadrajet as a performance carb . But rebuilds were successful if you JB the plugs that leaked fuel on the bottom of the float bowl . But the chrysler thermoquad carb was a night mare IMO .

Think im going to have to strip my 1404 carb on my cobra replica , let it stand for a few weeks with the new uk E10 PI&& they now call fuel, starts and idles well but just after idle it almost cuts out if you blip the throttle, never had a problem in 10 years with the old unleaded fuel, am currently trying to clear it by running 20 ltr of E5 super plus 99 ron with an injector cleaner in it......

How's does the accelerator pump hold up to pump gas ?

Hi I had a question for you guys what cylinder head could I use on a ford straight 6 4.1 the 250 cid help please looking to get rid of the log head

Try Pine sol for cleaner works great , also a rust remover ! I put crusted over Edelbrock in a bucket of pine sol and came out bright and clean then rebuilt it . Five years and still going .

Why does mine do fine when I cruise around town but when I go over 30 miles cruising at 65 and holding it starts stumbling then when I stop It dies. But fires back up without hesitation and stumbles as I take off. 350 .40 over, 488 lift cam, vortec heads, dual plane intake, 1 inch spacer

The 4 small jets in the bottom of the carb I definitely mixed up.. how can I tell which go where

But the qjet is a better carb if set up right great mpg and performance

i'll always go w a Holley

Who is Best? Q-jet or edelbrock 1406?

What do I do if my baffle plates are almost completely rusted away? Everything else is fine

Edelbrock makes about the easiest Home Maintenance carburetor there is you can pull one of them apart while it's still on your engine simply take everything apart with some spray cleaner and a blow gun on your air hose just blow through everything reassemble set it and forget it🇺🇸⛽🔧

i want more desert

The quadrajet with the j marking on the rear metering rods is the better carburetor

REJECT MODERNITY RETURN TO CARBURETOR

That was quite the abrupt ending.

The Quads mounting holes are not the only thing that's different the Quads entire manifold inter designs were made for the carp better off with a 50 buck used aluminum one. On a good Quad there wasn't a AFB or Edelbrock could touch it on a big Block Chevy.

Rebuilt several. Wasn't that bad

It is a common mistake when rebuilding carbs and those are the venturies brass extender that goes into the carb body they get clogged and create all kinds of problems . Take a set of players and remove from aluminum housing and clean good and reassemble it will make a lot of difference on driveability

0:04 "save big beaucoup dollars"?? Save big many dollars?

Where do you get that big can of carb cleaner?

Looks more difficult then a Quadrajet. Especially when he holds his hand infront of the details of the proper float adjustments. Maby a different video will help me rebuild mine better

The Quadrajet is a superior piece compared to the edelbrock. A tuned qjet is amazing, near EFI quality

I'll take the quadrajet

Were there any other spread bore carbs other than the q-jet?

#teamholley

yeah, did all this and still had a shit carb. soaked that carb in carb dip all nite.......did nothing to the hard candy like resin left behind by ethanol. i assume there was some passages that were clogged and no way to know so off to the trash it went.

Don't dis on Q-Jets!

Love the videossssss I'm a hugs fan I also have a 1980 eldarado cadillac hurse, but I would like to give an idea that I would see as fun, but what if power nation found the biggest carburetor ever and presented it??

This video is a bit of an oldie. 2014 i think.

You forgot AC Bristol or AC Cobra lol

The perfect video on why to buy a Holley carburetor

get a new aluminum intake manifold

wait wait 16:49 "Weber" casting? First time I see that. Someone could explain that to me?

Looked up how many pounds my car carries around per horsepower, almost 17 lol. Almost had a Javelin as my first car but the guy sold it to his buddy for less than I'd offered him

Pocket rocket .lol

Had a 1972 Pontiac Firebird and it had what everyone was calling “quadrapuk”. Ended up putting a 600cfm Holley on the car then

Some advice , if you want to rebuild your edelbrock , have a pro do it. Too many small pieces for a novice.

I purchased one of these EDelbrock carbs from a vendor that you speak of many times on your show. I had non stop problems with this carb. After 4 months of fighting with this POS I contacted said vendor and was informed that it only had a 90 day warranty. I now use this junk piece of aluminum as a doorstop and I will never do business with SAID vendor again.

4 represents power in the bible,spirit. Man has four limb's and the cross has four points, and the swastika for the dark side. There's lots more but I can't remember it right now. Iv noticed that this manifest's in engine's. Three and eight also represents power,eight rep's infinity and three is perfection,this the straight six is two times three and three cylinder's perform good.

😁🖖✌👌👍😎

2nd

I keep converting the edelbrocks for Q-jets, since the edelbrocks are pieces of crap!

the real content starts at 09:45

The best way to rebuild a carb: throw that 30+ year sob out and go buy a new one

Way too many commercials

You guys are very wrong about the "Q" Jet carburetor, as you don't have the knowledge to tune and make the necessary modifications that will improve the performance of this simple easy to modify carburetor. The "Q" Jet was manufactured by Carter Carburetor on North Spring Ave. in Saint Louis, Mo. for GM. I just happened to work there as an R&D Engineer. Not only that, I also trained Fuel Systems for thirty five years during the muscle car era. The "Q" Jet was designed for low end performance and fuel economy (small primaries with double booster venturies) and mid and high end power (large secondary bores). I often laugh when I view all the modern carburetor gurus making improper statements about carburetors. You have no idea what we went through to develop carburetors and calibrations. They are nothing more than analog computers, that operate and deliver the proper air/fuel mixture to an engine under all conditions. Edelbrock acquired the carburetor line from Carter-Weber and as far as I know, they still use all the original prints as a foundation for what they produce. I also believe they still use the same equipment that we used to develop carburetors.

I watched junkyard digs enough times to know a carb rebuild wont last.

Where is the hearse

Save money, grief, and your time. Toss your Edelbrock carb where it belongs, in the garbage! Quadrajets are not complicated and will run circles around the junk Edelbrock!

Quadra-Junk! Steel shafts rotating directly in the casting, no bushings. Once it's worn in, you're done for.

If you're having problems rebuilding any kind of carb, then just go efi lol

1st

Quadra-Junk. Bin it ASAP.

That Carb is TRASH.

You're better off just spending $300 and buying a new carburetor lol. I'm not about to spend a whole weekend and probably $100 in parts to be frustrated rebuilding a carburetor. Only to reinstall it and somethings screwed up with the body the last jack ass who rebuilt it damaged. Then you have to take it off and take it apart all over again. Trust me just buy a new carburetor. I've been doing this over 20 years. A rebuilt carburetor is never As Good as a new one lol.

Why bother, just buy a good carburetor

Calling a Qjet complicated compared an edelbrock Thermoquad clone... BWHAHAHAHA!!!

Edelbroken
