OK... So I call me crazy, but I could not resist trying some 44 mm chokes today. I know... major changes. But the idle circuit mixture did not change much. A little leaner... I assume that is do to flowing more volume which seems a little strange at idle. I tried leaving the mains out and running on the idle stack. Everything looked pretty good. Right about 13 - 14 AFR. Then I through in the mains, and I tried a bunch of different main jets but could never get the thing to even run on the main circuit. Always way to lean. Any ideas for a starting point for 44 mm chokes for mains and air correctors?

Thanks,
Mark
