I have a new short can pump and it appears that it might be blowing the needle off the seat on my quadrajet at idle (maybe). At times, it pushes gas out of the carb at the gasket between the base and airhorn. For now, I just want to confirm whether or not the pump is the issue. If it is and I replace the pump again, I'm going to run the same test right away. If it isn't the problem, I can cross it off the list as being the cause of my problem. And...... yes, I have done all sorts of other testing, tried other known good carbs that run perfectly on other engines, changed carb power piston springs, run vacuum tests, prayed to Jesus and said naughty words which made me pray more to Jesus. Yes, the other carbs were flowing gas out at the airhorn gasket too and worked fine on my other engine.
Thanks to everyone for the input. It's one of the few common things I haven't tried to test yet. The engine is being yanked and parted shortly anyway, but I'd like to see if I can drive it a bit for the remainder of summer.
