I'm definitely not a holly expert, I ran Carter's for 30 years but have been running Holleys for the last few I would be looking at the primary circuit and accelerator pump possibly. Good luck
thanks... I put in an 8.5 and it really opens around 7... the alleged 7.5 was just too late-opening. I need to make or buy an adapter so I can test PV's for accuracy.
Carters are just as mysterious to me as Holleys are to some ;)
