AVS2 tuning

Its possible I have it set to tight .

I dropped to .098 mains and the stock .065 x .052 rods and it jumped to high 13s... stopped and swapped for .068 x .0555 rods and now it is in the high 14s - 15.5 on a cruise at 2200 . But now it stumbles on light tip in of throttle. I will try stronger springs . The accel pump on this 800 came from factory on the biggest shot . (Hole nearest the body

Any chance your vacuum advance isn't working?

And appreciate the discussion/explanation of how this carb works!
