You need some good epoxy for the caps under the main jets that keep falling off. LOL
I cut out some pieces to put in the wells, in the base plate, to keep those things in place. One of the biggest P.O.S. carburetors I ever encountered. Heat finally got to that plastic crap after a few years. Most did not age well.

Newsflash! Now legal on all AMC's!

I'm pretty much retired. Have not touched a carburetor since 2010. My favorite carburetor, however.

I have raced and ran T Quads on the streets since 1971 never had one fail. I have had plenty of problems with Q jet. My dad had one on his 85 D350 never could get it to run right even bought a new one from Dodge. Put a TQ on it and never had another problem. I guess it is all in what you know. Now I'm fighting with the tempermental Holleys.

Holley are easier than Quadrajets. The problem TQ carbs were all on street cars & trucks. All old enough to need work. Those caps under the main jets falling off were all high mileage, several years old. When they flood on start ups, and you don't see fuel drop on the throttle blades like a normal carb, those caps are loose. Pull the carb base, and they usually fall out on the bench. Probably fixed close to a hundred of those. You could not run fast enough to give me one.
Making a fairly new TQ run well is no problem at all. Just plastic bowls failing on older carbs.
What is your Quadrajet doing wrong?
