Thanks for all your input. I did everything that yall suggested and you know what the problem was. My air box on the carb was to close to the frame so I put the filter right up against the carb without the box and it was flooding it when I had it throttled. I did not think that the filter could block it that much to make it flood. It is a new motor but I just couldnt resist full speed. The mixture right now is still 20 to 1. Thanks everybody
