I notice a loud popping at high rpms when I let off and grab a fist full. I don't have any leaks any help would be greatfull.

 

Turn the mixture screws in all the way and back them out to 2 1/2 to 3 turns. That should get rid of most of it. It is caused by too much fuel biulding up the the exhaust system. By turning the mixture screws out, you lean out that condition.

 

Is that both air screws at 2.5 to 3?
