SUCCESS

Drilled out IFR from .037 to .039. Test drove and things were very close. So I went up to .040 on both the primary and secondary.

The car drives fantastic. Crisp response at all speeds and no lean surges.

Everything else in the carb is as delivered from Quickfuel.

If someone is interested in the breakdown of parts in the carb, I will post it.

I am disappointed with expert advice from several sources. If I had listetened to them, I am not sure It would have gotten fixed. What does the average Joe do that doesn't know anything about cars?

Ultimately, I had to brush up on my Holley tuning experience and purchase many more jets and air bleeds than I wanted to get this fixed.
