my truck failed emissions today very badly. probably my ignition not strong enough for larger plug gap.
and anyway my carb had problems and i got a HOLLEY 2210 (R 7666 told for a chevy) on ebay. and put it on my intake with no vac or fuel leaks. and linkage lined up easy.
it did start right up. but then for a while i had some trouble starting it. i have pcv vac hooked to carb 3/8 and what i hope is the vac advance to a smaller vac inlet with some sort of resistor jet in it. it runs better than old one but im not sure how to tune it.
any tips about being certain i have correct timed spark vacuum hooked up to distributor especially appreciatedd
