Re: Hello from Pennsylvania
From what you are saying, it may be starving for fuel at higher rpm's. Are you sure your gas valve is on all the way, and not half-open? Is it still in break-in period (first few tanks of gas)? You may have to adjust the carb some more to get it how you like it. check the color of the sparkplug, it should not be too dry or too wet either, try searching here to find some good answers.
