would it benefit going to larger hole for clearing up idle somewhat with heavily ported blocks ,I know it will let more air in but it looks to be marginal ,I have to throttle to 2 k to clear it out then let go of throttle when front settles back down then stab it and were off I tried larger idle jet then it will sneeze some times when temps are low 70 ish and off idle but still loads up some ,something i,m pondering
