I've got an 82 with an unknown quadrajet sitting on top of it. When you put it to the floor it will spit and sputter and almost stall out, but if you feather the throttle into the high rpms its fine. Plus, it seems to only really bog down while its in gear. I wanted to hit a bog on Sunday and don't really know a whole lot about the tuning of a SBC. How do I determine if its carb or igniton? I've adjusted the timing and can't seem to get the hesitation out.
