The weight difference is the Holley is made of a zinc alloy called Zamak (trade name, many variants), the clone is an aluminum alloy. Many carbs are. Hence why many suffer from zinc pest to varying degree, depending on the specific alloy. Its used due to its very high suitability for die casting. We have better aluminum alloys now that have displaced Zamak some, but its still widely used. Yes, Zamak contains aluminum as one of the alloying elements, and is very often confused with aluminum, and sometimes referred to as aluminum by manufacturers to avoid calling it "pot metal" (aka Zamak), but its primary element is Zinc, hence the weight difference. Also, the number difference on jet sizes are metric vs imperial.
I got some Chinese made motorcraft 2150 copy off Amazon for $100 or so because my original carbs throttle was hanging open slightly no matter how much I cleaned it and it would cause it to idle too high. Looked over it made sure all the screws were tight and adjusted everything to where it needed to be. A few months later still runs perfect, no issues starts right up with one pump every time. This was more so a temporary fix while I save up to get a nice 4 barrel intake and carb. But for now it’s doing me really well.
@cyber3167 very good chance your original throttle shaft could be worn causing a vacuum leak causing the high idle. I’m pretty sure the autolite/motor craft carbs have a rep for that
Ordered me a Remaned carburetor off of rock auto for my Jeep cj6 with a 2100 Motorcraft. Cost me near $300 but we couldn't ever get it to run worth a crap on a Low mile 304 engine. 45k Shoddy rebuild from Autoline products in Canada. Wore out shafts and a warped flange. No help from Autoline or Rock auto. Bought a 70$ 2150 knockoff from Amazon. Cleaned it and adjusted the screws and drove for 2 hrs that night. Ive been thinking of going to a 2300 500cfm or even a smaller 4bbl since I street drive it for the most part. I'll probably try of these before I dump $300 again on something that isn't worth a Sht.
Actually quite a few nice upgraded compared to a standard 1850. The extra jets are to get you tuned for the fuel you intend to use. They don't don't know if you'll be running straight gas, 10% ethanol, 15% ethanol...good job providing some tunability. Good upgrade over the holley cork gaskets on the mixture screws. Nice removable air bleeds. Brass float is cool. Bushings on the throttle shafts-nice. Lightweight alloy-a plus. From what I see it looks nice. Probably very easy to tune
It’s fluff. The true understanding of how this thing is going to perform is in that god awful metering block. It’s unbalanced at best. It’s not going to be easy to tune, if we can get it to be consistent at all. The proof is in the data. The first half gathered in this video, sucks. We’ll see what it produces once we put it on a mild small block. Stayed tuned!
I'm definitely with you. Not buying Chinese knockoff anything. American made equals better quality faster setup and long-term reliability and no screws going down the intake manifold.
The stuff they spray in there and on the out side is like a creasaul because they are shipping over on a boat the salt air dosent effect the aluminum,,same as on cars they ship ,you see it on the brakes and rotors any thing they think can get exposed to the salt air
Great info I'll stick to Edelbrock and Holley, look forward to seeing the test drive, hopefully it doesn't leak fuel and your GMC catches fire maybe throw it in the iron pile to be safe as always keep the videos coming, good guys in Puyallup is next weekend I'll be there
@@johnweaver8470 man I wish I could join you! Such a great event and an exceptional venue for it. Maybe one of these days I’ll get back up there. Have fun!
Friend just bought one of these to replace a Summit brand 600cfm on his car. I installed it on his SBC and checked float levels and set the idle/air mix and it seemed to run fine. Shut it off and tried to restart it, but it wouldn't fire up. Poured some gas in it and it fired, but popped and died when I tried to give it gas. Looked at the primary bowl and no gas in it. Secondary was right in the lidle like it should be. Pulled the primary bowl off to check float and all seemed fine. Put it back on, poured more gas down the carb, and it started again. Primary bowl filled to mid window and then watched as the gas disappeared from the window again! It seems the needle or seat occasionally sticks and it runs out of gas. After a couple hours of screwing with it I removed it and packed it back up so he could send it back. It's just junk. Bought a rebuild kit for the Summit carb, and rebuilt that instead. No more problems.
5 or 6 years ago I purchased a turbocharger from Chinese company for $160. The Borg Warner direct replacement was 1,000. Guess which one win in the car? When Borg Warner buys them they buy them from China, of course there's more testing and oversight but most likely that's the reality. I must have gotten a good one because these years later it's still working. I do however agree with you I would not put the carburetor on my car.
I like ur assessment of this carburetor. I know there's a lot of things that most people would not know if it was good or not. Saving money on this carburetor will just get you in trouble in the long run that's for sure.
@@VinoRatRodbuilds i completely understand saving a few dollars here and there, but yeah you nailed it. In the long run it’s gonna be more trouble (and money) than it’s worth.
If I built a fair amount of engines ,I'd get one and use it ,along with some other cheap parts like some tinfoil headers. Run it on a test stand first before giving it to a customer or dropping it in your ride and finding that rear main oil leak after the fact just sucks.
I'd like to see it installed on a running engine...it's one thing that bothers me about you tube. People rebuild a carb but never show it working on an engine... If Putting it on an engine drives the death nail in one of these knock off carbs so be it.... Same for some one doing a video on a rebuild... I don't fear failure...as it is the ultimate teacher.... As always you do a great job pointing out the details.
@@moparnut6286 time and understanding. The two things I fight. If someone buys a knock off expectiing to get a copy of whatever, I’d be under the assumption that they’d expect to have an understanding of what they’re receiving. Capable of running or not, with this carb, you’re not getting what’s expected. I’m sure at some point when I have the (time) we’ll show these on an engine and show the data. The (understanding) sets the expectation of performance. One has to come first! Maybe one time I’ll start with the result and go back and get the reasons why in a second video. Stating with the understanding at least points me in the direction of what’s going to happen when we do run it and I won’t run into an over or under fueling situation and hurt a good engine. I know with this one, I’m going to have to watch part throttle AFR closely and for sure transition AFR with that smaller PVCR. Don’t think this one is bad enough to kill some timing, but I’m guessing it might. Wouldn’t have known that without the knowledge first! All I’m lacking now is time……. 🤘
As an European driving an american truck I stick to OEM parts as much as I can. In Germany it is very hard to keep US cars running, because those are very exotic cars over here. For example you have to take them to one of the very rare specialized workshops for repairs because normal shops do not touch US cars. It costs way more money too, 180 dollars per working hour at the shop is very normal, and you have very limited access to used parts. Every two years big discussions with the dudes from the technical inspection agencies who never saw an US car if the car is roadworthy or not. My Truck is halfway illegal due to the fact that spare parts for the truck do not have an european proofmark on it. If the cops stop you and decide that your Walker standard replacement exhaust has no proof mark and therefore it is illegal, your journey comes to a sqeeking halt. It gets towed away for a new technical inspection and a juicy bill for the whole shabang. And you can lose your drivers license for that too. For a tire shop it is somewhat illegal to bolt on bolt centered wheels because the standard is hub centered wheels. The list goes on and on. Pulling the chinese wildcard is no option at all...
The difference in jet sizes and other restriction sizes is neither here nor there. A 600cfm carb can have any number of combinations of restrictions depending on the exact engine and chassis package. Even two identical cars but one has header pipes and a different intake manifold could require complete different jets, pvcr, accel pump, power valve and air bleeds, but both have 600cfm 1850s. You have to tune them for what you have. Nice of them to give you some extra jets or air bleeds.
@@landoncustomclassics check back in a week and see all the people completely ok with buying a knock off. It’s rather remarkable actually. This one is not great, but of all the knock offs I’ve reviewed, it’s probably been the best.
@MuscleCarSolutions I buy the like $15 lawn mower carbs. They've done ok. My brother bought a knockoff for my dad's Honda 4 wheeler. It wouldn't fire, but ended up being the tps sensor so we put the old one on and it's worked fine.
DHL ain’t much better. Plus they aren’t very friendly going through customs, no matter what the carrier. And don’t put statements on the package like “fragile” or “do not bend”. They take that as a challenge! 😳
Thanks for posting this video and breaking it down. I bought my basic Holley 3310 in classic finish back in 1996 for $189. Now, as of the writing of this comment, the same carb is $574 from the Holley site (subject to change at any moment) and the 1850's aren't too far behind that. As a consumer, it can be tempting to fall for this crap because the price is so low but there's something so fishy about it and you did a great job with your video of exposing the utter garbage one can end up with if one falls for the "too good to be true" marketing. I am curious, were you confirm if the threads on the jets, power valve, bowl screws, idle screws etc. are SAE or metric? It would suck if this was discovered part way through a jet change or a rebuild.
Price of everything is up these days. Still plenty of cores available if it’s a carburetor you’re after. The amount of these knockoffs flooding the market should be criminal.
Case in point, especially when I'm dealing with like the situation. I'm dealing with people coming up to me and wanting me to work on their motorcycles and finding out there. A Chinese knock off of the Honda, 250 or a scooter or a Yamaha, 250 or Kawasaki, 250. None of the parts will interchange.They're very close but not at all. They even even go so far as look similar too
Thanks for the Video....I agree with you...USA...I try to buy American Made where ever possible. However that being said, sometimes you just can't. I have a Lawn Mower that Briggs and Stratton no longer support. I had no other choice but to buy a cheep knock off from Amazon. Surprisingly, it works better than the original ever did even when the mower was new. Mower fired on first pull and everything fit just like the original. And like your example, they included extra parts, gaskets, screws, even an air filter. and spark plug. Faced with buying a new mower or fixing the old one, the choice was easy. Less than $25 vs several hundred.
Jets are 'flow rated' Holley did that for a while and everyone hated it. I have done a China 350 2 bbl. Needle and seat was stuck which is common from being on the shelf. Used all Holley parts in it. Crappy finish but I had no complaint so I guess it was ok. Holley jets fitted but I used the ones it came with. Most Holleys are alloy these days. I have just bought an 850 Edelbrock and it weighs around the same as a diecast 3310. It seems some of it is alloy and some diecast. Read the Holley website, there is a dozen versions of the 600 and they all use different size mains. Ditto with a 750 d/p. I normally use those numbers to make the carb original again. So many idiots use small jets to gain economy,, and melt the engine or use bigger jets to go faster and usually end up way too rich. Though a dyno is the only true way of jetting. 350 Chev race engine with Dart 2 heads and a Victor Jnr,, 830 annular. as the book said 80s all round and it was good on the dyno. Went to Victor race heads with a 2925 intake and had tp go down to 76 all way around. The intake system was all far more efficient and required less fuel to do the same job. And it had over 40hp more and was far livelier from 5000-7500. But had nothing under 3500! You will find the Holley gasket does fit. 1850 and 1860 use a different gasket.Those bowl and metering gaskets are plain junk. As Holley ones used to be in the past! Holley have got way too expensive and have been for quite a while. So really do not deserve any special treatment. 650 spread bores are made in Japan! Would I buy one? Maybe for a stock engine, that is after I have been right through it. Though that costs money and time. I feel sure it would do fine on a stock gunker. Performance engine? Never. But a 4160 is never a performance carb ever.
You are measuring wrong. there is no way you have .081 emulsion. Are you measuring the lead in hole? Th emulsion bleed is at the bottom of the lead in holes. should be .026-.029
BTW I am driving this "very rare" 98 Ford E 150 Club Wagon. There are less than 100 around in this country. People call it a "Chevy Van" or "the A-Team Car" because they don´t know better. Normal people never get the chance to see the difference, it just does not happen that US trucks are parked next to each other on the street. You may see one of the very rare F 150s or Ram 1500 from time to time over here...
It looks to me like the carburetor wasn't so much modeled after an original Holley carburetor as it was copied from an aftermarket upgraded version of a Holley design. Can't wait to see how it works on an engine, how it actually performs.
jet sizes are 100% metric - ie 0.064in = 0.165mm That said, would be interesting to see a dyno test with size/type equivalent Holley carb (granted that the hardware was all pre-checked to make sure none of it goes through a motor. My gut says this won't produce the same numbers or the repeatability that can be had from a quality carb.
My experience with knock off carburetors is there’s no money saved. The headache of tuning those carburetors is not worth it. I’ve only dealt with motorcycle carburetors but they’ve been difficult to tune and finicky. That is not what you want.
It’s actually drilled with metric drills 1.65 mm 1.70mm 1.80mm 2.00mm so the number is exact size in metric drills well as good as china drill bit tolerance can be lol
just convert metric to imperial so add a decimal after the first digit to chineese numbers it makes sense 2 mm is almost exactly .078 of an inch... and while not EXACT conversion it's close on the others also. 165 is 1.65mm etc etc.
I've never been happy with the low end, off the line performance of Holley carbs. Yes they do perform well in the upper rpm range and on race applications but I would always prefer a Quardrajet carb for an everyday street vehicle. The smaller primary style just feels better off the line and when the large secondary open when you mash it you know something happened. I also don't care for the Chinese knockoff carbs. There is always something strange in their thinking about how to meeter fuel. Great video. I enjoyed it very much. Definition of a carburetor = An attempt at controlling a fuel leak!! 😂😂
I work for a auto body shop and they buy the cheap Chinese knock off parts and I assemble cars and I'm always dealing with poor quality parts and fitment there is a reason they get the knick name cheap knock off lol
@@andrewforster4974 I was a manufacturers rep for quite a few years and had a client that brought in collision repair panels and parts. All China and ridiculously cheap. The mark up in that industry is insane.
To anyone looking into buying a knock off carb to cheaply got a project going.. please don't. U can buy quality name brand carbs dirt cheaply on the used market. Pretty well every town has atleast one old man garage with several carbs laying around. Holley stands by their used products and their customer service is happy to help with any holley carb regardless of age or how much u spent on it.
Good review mate. I buy whatever gives me best value for money. As you have shown, the Holley is probably the better product, simply because you can get the parts for it, even if this carby worked we'll on an engine. I would be very interested to see how it actually runs and performs on a standard engine, as that is obviously the market it it aimed at
I’ve done a number of these knock off reviews. Sometime I’ll rotate them out and do a quick review of on engine performance out of the box and with what limited tuning that can be done. That’s what will end up killing them. There’s just no further support if someone actually wants to get them to run at their optimum performance and economy.
The hardware they signed with you is probably a standard kit. They sent with all those type carburetors whether it has a choke. Cable or not, the hardware kit is pre-made for that. Technically, the choke electric choke version and they just send it in every kit. Even manual joke
Can you drop a Holley metering plate in and put in a Holley rebuild kit since Holley is running carbs @ close to 900 bucks for a carb that needs a lot of work to use it brand spanking new. Run it on an engine at least after you go through it like new Holley requires. Sure we are all sick of Chinockoffs, but in the current market where inflation and American companies are charging far way to F'ing much for products trying to maximize their profits to the max and at the same time crappy support and no available product making you wait months. I have waited 5 months for my CompCams camshaft which I switched from Lunati since they could not give me a delivery date which was waiting months for, so I switched to Comp to only get screwed again. The rocker arms are still back ordered until Sep 28 when I ordered them as "in stock" on April 12th. Stop knocking people who need to get their old car running as economically as possible when you do not highlight the companies ripping off Americans, providing shizz support if any at all, and taking half a year to get the product.
I appreciate your videos! If you do a deep dive into Temu you’ll find most the products are made and shipped from areas of China that are rife with slavery. Barely sociable here on YT did a good video on it.
@@ToddMcF2002 oh we’ll put them on my mild small block and I think based on how unbalanced that metering block is, it will be very inconsistent. I’m sure even with the datalog there will still be plenty of people willing to support it. Maybe this fall we’ll do one video with all the knock offs back to back to back.
I got one and it sucked the accelerator pump didn’t work and after I fixed that it ideled ok ran ok light throttle but give it a some heavy throttle and gust shut down. I swaped out the Bowles on to a good old Holley body I had and it runs great with that carb body and the bowls off that pic of junk.
people with the knock-offs are saying they don't care about the future their kids will one day get to experience. you can't get much cheaper than that.
What gets me with these is that Asia is been well known for decades at being fairly good at just making a 1:1 copy of an item......(usually its captured military equipment). Why they went to all this trouble without just making it an exact copy is beyond me.
@@stevehilligoss4982 depends on where you look. But without a doubt the last 20+ years have not been kind to US manufacturing. Given the cost of everything going through the roof and labor at an all time high. Insurance, consumables, raw materials. I’m thankful I’m at the end of my career and won’t have to deal with this much longer. I’m all for higher wages, but it does put a bigger strain on a system that was tipping towards the edge anyway.
I would LOVE to save money on an Ikea-like carb "kit". Hell, if I can buy a Holley HP for 1/2 price.. I'm IN!! But.. THIS? NO. Mostly because you can't get off the shelf replacement parts. This is great if you're just trying to get an old car running, but it's not for every day driving.
@@neilkratzer3182 had to know what we were working with before the install. That way we know why an area in the rpm range works or doesn’t. Part two coming up where we put all these to a simple initial adjustment and a road test with AFR data. Stay tuned!
In all my experiences I've ever seen.When it comes to knock offs of any kind they cannot do a hundred percent 1 for 1all the cross the board due to patent infringement and possible lawsuits
The jet sizes are going to be metric. So will the air bleeds and every other dimension. All the passages and slots are going to be sized promotional to each other. You can't really compare component dimensions apples to apples. This looks like a well thought out carburetor and the fact they provide multiple jets is great. Also their castings look very good and a bunch of features are better. The transfer tube, sight glass, and mixture screw seals come to mind. Feels a lot like you're looking for things to nit pick. It's laughable being upset about a knock off of a carburetor design that old and it's not like holley is a mom and pop speed shop struggling to get by.
I think, these numbers are jets flow on test bench, maybe cc/min with 1 metre of water column. Sorry for my language, I'm not native speaker. P.S. And my choice for my old cars are Edelbrock AVS2.
I’d love for that to be the case, but I’m guessing any high tech testing equipment isn’t on the menu for these knock off companies. Make them cheap and get them out the door is all they care about.
I wouldn't run that on my worst enemy's car. You're just about guaranteed to end up with a butterfly screw in a cylinder somewhere. Which makes that a VERY expensive carburetor. And I'll bet the metallurgy is all over the place. Would be interesting to see how long it held up to ethanol....
@@MVPisME383 prices rarely come down but man are things ridiculously high these days. Hopefully once inflation is better under control we’ll see some prices drop.
You got it. Knock off is just steeling someone else's research and design. Good luck with rebuild parts. I stick to a known Holly. Thanks for the review.😊
One word JUNK. I bought a knockoff street avenger for a dump truck that had been sitting for ten years just to see if i could get it running. It is what I expected it got the truck running, but I will never buy one for something I care about.
Temu can sell so cheap because they compromise your personal info including selling CC numbers . This has been documented., and can be checked out with a couple key strokes.
I find that anytime there is a knock off of a product is because companies have decided to have their products made in China instead of USA. This is why manufacturing needs to be brought back to America.
@@BPattB eBay is just as bad and they refuse to protect American brands. Their VERO program to remove knock offs is a joke. I rarely use eBay anymore and I used to drive all my sales through that site.
I wouldn't buy one, but the holley on my car was 720.00. This one was what you said, 90? This is why people go China. Can't beat the price. I AM guilty of buying a Chinesium carburetor for my mini bike😊
@@MuscleCarSolutions thank you for these awesome videos and don’t pay any attention to those folks that are to cheap to listen to you they will regret it because the screw fell out of their cheap Chinese carburetor and blew up their motor !!
@@jimstern4244 not my engine! But I hate to see folks make bad decisions thinking it’s going to save them money or time. All I can do is provide the info. Thank you! Very much appreciated. 🇺🇸
@stevehilligoss4982 the cork is there to seal it. It had a black rubber one on this carb. The additional o-rings aren’t necessary. Unless there’s something more awful to this carb that we haven’t experienced yet.
