My engine came with a quadrajet. Not sure if it is a stock one, although I don't think so. It starts up great, idles great, choke works. While driving and trying to pull a hill it bogs out and won't go into the secondaries, and has stack fired a couple of times. Should I take it out and go through it with a complete overhaul or rebuild kit or should I try something else? Just want everyones opinions. I'm not partial to any one carb, just want one that works good. Wouldn't mind keeping mine if it can be fixed. Carbuerator is installed on a 1969 buick 350. Thanks Everyone
