Will a new $150 'knock off' Rochester Quadrajet Carburetor work? Let's install one and check it out.

I install a new $150 "knock off" Rochester quadrajet 4 barrell carburetor on my Chevy 350 small block that I bought off ebay. Will it work? (not sponsored) Honest review.

With a little tuning these ChinaJets work very well, used one on a 500 Caddy .

I'm 74 years old and I've been rebuilding carburetors for people forever and quadrajet thermal quads Holly's I'm the only carburetor guy left in this particular town here in Texas and even a Snap-On tool that says hey you know what you're the guy the only guy we got left to that rebuilds any kind of carburetor you can bring in I still still doing make modifications to him also and yep yep yep I don't have any more years I'm going to keep doing it my eyesight starting to have no problem

Two known but very fixable issues with Q-jets are the foam float, change that to brass and set the level cost $10.00 or less, and another lesser known and also very fixable issue is the well plugs between the throttle plate and the float bowl, remove the old press fit lead ones and install the repair kit (cost less than $10.00) with two aluminum plugs with O-ring seals and problems solved -- the Q-jet is an excellent carb if youre familiar with how to sort them.

I been running the Chinese knock off motortcraft 2150s on my fords for a few years. I’ve had real good luck with them.

Older quadrajet chokes were always in the intake manifold like yours, finicky to adjust but not that hard just WATCH VIDEOS on Q-jet rebuilds and you'll be surprized how easy they are to work on, I was rebuilding them when I was 16, I just bought me a manual that covered all the carbs from my era (im 64) and learned that way, I didnt have the internet and youtube and the internet, its even easier today with the internet.

Quadrajets are a great carb and easy rebuild, lots of information, books and support out there.

Should put throttle return springs on like the factory had them. Connected to a bracket across that mounts torear carb bolts and the springs connect to the bottom of the throttle lever below the throttle shaft and pull straight rearward closing the throttle, The way you have it way out board will cause premature wear on the throttle plate bushings and invite the possibility of the throttle sticking full throttle if it cams over the pivot point with the spring at a angle

Glad to see someone with as much junk as me in their yard, only I’m in to old Trans Ams. Always carry a fire extinguisher in them old carbureted cars.

The real test is to see how the secondaries open up when you tromp on it.

Hey Bud thanks for the video I have a 1978 Chevrolet c10 Scottsdale I was on the fence about buying a original reman quadrajet for 485 dollars can't afford it so I bought a on eBay and it works great. Thanks for the video.

That Aspen RT super coupe has my mouth drooling 🤤 we had one bought new in 78 and my brother fell behind on payment. I've looked for one to build since. Very nice cars. I had a 77 nova rally that I raced. Great cars

A fellow shitbox enthusiast with jeans that look like hot garbage. This is my kind of youtube channel. Thumbs up!

[Mike-xtot]

Enjoy your channel alot.
My brother purchased a aspen super coupe new and it was one of my all time favorite cars. The wheels are the best looking factory 15x8 ever. Wish I could get one.

The Problem with one of these "replacement" Carbs, is what was Fuel Delivery Curve set up for? The Q-Jet was offered on tens of thousands different Engines and HP ratings, and few had the same Fuel Curve
If the Choke is NOT opening Fully, the Secondaries will be locked out, so your Bimetal Choke, with the Welded Link is Questionable. The Old Carb looks like pre 1975 chevy, Calibrated quite Lean, and all the Jet changing in the World isn't gonna Richen it much, in regards to its tip-in Delivery. Some serious rework of the Non-Service Parts of the Fuel Bowl need recalibration
The 'New' Carb has an entirely different Choke Mechanism, far less sophisticated

The Idle Solenoid, wasn't just used on A/C cars, it was often used on non-AC ones to prevent/reduce Dieseling when the Engine was shut off. In the early 70s, lean Idle Mixtures combined with retarded Timing, required a greater opening of the Throttle to attain Idle Speed. When the engine was shut off, more air and thus Fuel was still moving, and the Higher Temps from the Forementioned Parameters would often result in the Engine kind of continuing to run without spark. The Solenoid would shut the Throttle in an Attempt to Starve the Engine of gas-air

Big difference on the Linkage between the Primary Shaft and Secondary Shafts, Angles are different too

It seems to run not too bad, out of the Box. It will be interesting how it runs at higher Speeds, keep us informed

Glad the carb worked out for you. It's 60 year old technology with no electronic parts and by now I'm sure the knockoffs are OK. Did you notice any weight differences between the carbs and the knockoff being lighter?

[foxisretrofitting]

I want one of these Chinajets so bad for my '79 Chevy Van. I've been rotating 3 ancient Q-jets and their parts for the last decade and I'm tired of it. An all aluminum fresh start would be awesome.

[tommyjefferson]

One thing it still does some awesome burnouts

[ricksoldcargarage]

With these new ethanol fuels have to see how it holds up.

[stevegordon]

I have a Chinese knock off ford 2 barrel works great did have to grease gaskets on power valve plate. Other than that small leak. Works great.
