Custom10, I brought up the vac adv question because White performance told me not to use it. I wanted some confirmation from some of the expertise I knew was on this forum. I have always run my circle track race motors at 34* total with no vac adv and the advance numbers seemed very high to me with vac adv. This new motor was a large investment for me and I didn't want to burn it up. I have seen the results of too much timing in race motors. UGLY!

Update: I jetted the carb up to 76 on the primary and changed the primary nozzle from .035 to .040. It was nice out today, so I took the roadster for a ride. These changes got rid of the hesitation and the bucking or surging. Don't know which change helped, but the car runs like a raped ape now. Again, thanks to Cobalt327 and Custom10 for all the help. I am very happy with the results.
