K truck is a 81 d150 354 gears, headers com cam, Eddy 4brl intake, nothing to extreme. Carn is a Holley 600. Problem is if u stab the gas at a stop it pops an dies or if I let off as soon as it pops it's fine. I swapped the 65 Jets out an swapped to 61s as that's what I was told to do. I'm still running the #31 squirter an am thinking of swapping to a #28.. truck fire up an idles great! I have been told the 31 is just a bit much..timing is dead on so only thing it could be is carb related. Any help would be much appreciated
