There's a lot of merit in that statement. With the Q-Jet, if the castings match, and are in good shape, you can make something of a reman. You pretty much toss everything but the castings. There's a couple of holes they plug the feed air for the idle speed, and that causes them to run really rich. They usually cut the pin off of the power piston, which kind of ruins it, because that allows it to pull too low, (that pin sits on the lever for the Adjustable Part Throttle screw, doesn't really matter for a racing carburetor) but that's not a big deal in many cases, and it's a replaceable part.


I scavenge for every single part, I never toss anything usable, so I have a big tackle box of parts, and a couple of crates of complete cores and castings. So if I can score carburetors or parts cheap or free, I jump on it.
