Re: reed valve or carb. problem

Sam.... The clue is in your statement of: "i place my hand over the carb. opening it when pick up speed and run good."

That indicates that the craburetor is fouled. clean it and pay particular attention to the brass high speed jet that is located in the bottom center of the float chamber..... make sure that jet is perfectly clean. I clean them manually with a piece of single strand wire.
