I have an 84 chevy K10 that I put a 350 in. After building the motor and bolting on the carb, I can't the truck to idle. It'll idle for a short time then start to die like it flooding out. The fuel is runnig at about 10psi. Or at least I think it is. Used a tire guage. Only thing I had. At this point, the only thing a can figure is I have a vaccum leak in the vaccum advance. Any ideas as to what I might be looking at?
.060 over
flat top pistons with valve releafs
slightly bigger cam
I think part of the problem could be in the carb tuning but not the best at that.
