My recently installed reman. 1 barrel carb stalls occasionally from a dead stop once I shift into gear(c4 auto). Revs just fine in park or neutral with no hesitation at all. I have a 6 banger on a 65 coupe. From reading previous posts it sounds like a accelerator pump but looking through the posts I cannot tell if this pump is adjustable, fixable or only replaceable. What do I do and where is the pump located? Most of the time it will run just fine but if I sit idling for more than 30 seconds or restart my car after sitting for only a few minutes, it will stall repeatedly for a few minutes then run just fine. Really need some serious answers before I stall out again and get rear-ended.
