I set my valves to .006-.008, and on the front cylinder( I believe) I am getting intake valve float starting at about 40 mph.  Anybody else ever experience that?

Thanks, Bob

It is possible.  Anyone else have a valve float issue?

I am not sure which cam is in the motor.  Things were going great and then the issue started where I was getting positive air flow out of the carb and a loss of power when that starts.  Only happens at high rpm.  Motor runs like a watch until higher rpm all of a sudden.
