No one has mentioned, but one of the biggest issues with Quadrajets is the float. I learned this the hard way years ago when I tore one down several times, and finally took it to a guy and asked him to rebuild it. The next day he had it done, and told me the float was saturated (he weighed them), so he replaced with a brass float. I always buy kits with brass floats now, and no more issues with floats. If your has the "fiber" type float, and it has been in there a while, my bet is it is heavy and or sunk. Also check primary throttle shaft for play.
