I can't envison anything after 1970 having the old coil spring choke control that just screwed to the manifold, but I'd think it was as one of the images that J Chicago posted showing the heat tube to carb.
I wonder if (all things now point to carburetor in my thinking) it is vaccum lock occuring in the throttle body of the carb, hence rebuilding. Been a LONG time since I've been inside a quadrajet.
One thing to check is with the air cleaner off, try to wiggle the carb left to right, if it moves, there could be your problem. If it dosen't it still could be a gasket leaking air into the carb, past the venturi, either way, it's I'd suggest carb overhaul. I believe the quadra jet has the hold together screw head from the bottom (manifold side).
