    78 c20 quadrajet problems

    Did you spray carb cleaner around base to search for vacuum leaks? Primary shaft may need bushings to prevent leaks. Did you keep correct original jets and primary rods in that carb? These heavy truck carbs were calibrated much differently than most other Quadrajets.

    Occasional fuel loss?

    JB weld won’t hold in the carburetors. We see it often, because it is easy to find and buy, but will peel off easily. We use a 2 part marine epoxy that has to be filed or ground after it hardens. For stubborn leakers, we thread the well and screw in plugs that are epoxied. That being said...

    California Quadrajets

    Calibrations were different but the Quadrajet can be set up for whatever you need to do. No other carb differences between CA and non CA.

    Polk Street Cruise- Amarillo TX

    Way back in the old days, we cruised up and down Polk street looking for some races. Always a good time.

    Carbs at local auction

    Center ones look like 4 jets, the predecessor to the Quadrajet. Legit appears to be old Carter AFB, same as the current Edelbrock. You can get your money back out of them plus some. AFB will have code stamp on front left of base. 4 jets should have a tag but most were lost.

    Quadrajet, fresh built for small block. Ready to run

    Well, hopefully this one will sell and we can build you another one when you are ready!!! You can save a little by not getting the plating. We do the plating on all of our "for sale" builds. Most are custom built to order.

    Quadrajet electric choke problem

    Ok. Then if the rear pull off has the two rods connected, you don't need the front vacuum unit. The screw mount holes are there, but it isn't needed. That bottom black rod is connected to choke mechanism and works as the pull off. Green rod connected to air valves works as the vacuum brake...

    Quadrajet electric choke problem

    From my notes, the 17056226 should only have the front vacuum brake pull off. You may have a reman carb where parts don't match original. Hope not, but the pictures will help.

    Quadrajet electric choke problem

    Do you mean 17056226? I don't see a 17086226. Post a picture of passenger side pull offs. If you have the rear mount vacuum brake with 2 rods, you wouldn't need the front unit. If your choke moves some when warm, you would need to re adjust the choke to full open when warm. If it doesn't...

    Stock jet size on a quadrajet for my 454

    Numbers are stamped in main body, driver side above secondary rod. Should be something like 17057229 or similar.

    Spreadbore Holley Carburetor ?

    If it has computer control, it probably can't be removed. It can't on the Quadrajet. Quadrajets aren't sexy? Aww, cmon.

    Stock jet size on a quadrajet for my 454

    Do you know your Quadrajet code number? That would help. I could tell you original jetting. Most of those had huge main air bleeds and were very lean set up original. We would typically use a 76 or 77 jet and many had 53 primary rods.

    Spreadbore Holley Carburetor ?

    I have several on a bench. They weren't very well received by the market, don't see them much. Holley type carbs have their place in the performance world, but not sure they did well with this design at all. If you have spreadbore intake, better off with a Quadrajet in my opinion.

    Quadrajet?

    If your truck doesn't still use the ecm connected to the carb, you would need a different, not computer controlled unit. The Quadrajet should be a great choice for you.

    Quickfuel vs Holley

    Thanks for the mention. I do sell Quadrajets with electric choke element. Many of the late 70's early 80's Chevy Quadrajets were hot air, or electric choke. The hot air units have choke mounted on side of carb and can be converted to electric element. I do a lot of these for people wanting a...

    Need Help with Quadrajet Auto Choke

    The pull off is supposed to pull in at idle vacuum. When it is pulled in, it should prevent the choke flap from closing all the way, since you need some air coming in. The amount the choke is left open is adjustable. What is your Quadrajet code number? I can help you with how to adjust.

    Air Compressor lines

    I used that rapid air system in my shop. It was very easy to customize and it has worked very well for me. I rearranged my shop and just took it all apart and then reconnected after all the changes.

    Carburetor Problem

    I can't see the entire code stamp, but it is a Chevy truck carb, from mid 80's so could be correct. It needs electric choke coil for choke to operate. You are also missing the secondary vacuum brake rod. It connects to the rear mounted vacuum brake. I have the parts you need in my online...

    Electric choke wiring

    Any key on power source would work. Don't use ignition wiring though. Best would be to use the fuse block if you can.

    Off road carb setup

    I have seen those for the AFB carbs, now Edelbrock, for off road. Nothing like it for Quadrajet, but not needed. Quadrajets have the center bowl so they do well in extreme angles because jets are always under fuel at angles.

    Throttle cable

    I use that Lokar cable on some of my cars. It has worked well and is smooth. Lighter return springs may help also.

    Anywhere I can buy a axle truss like this anymore?

    I was looking for some recently also. I had them on the front and rear of my 76 Blazer way back when.
