Sounds like a vapor lock.

You using a vented gas cap? If not try loosening your gas cap and see if that helps. If that helps get a new vented gas cap.

Also is your float properly set in the carb? Could it be sticking closed?

Thanks for info ,I will check for vapor lock from fuel pump to carb.when I get it fixed I will let you know what The problem was.thanks Mike


I go along with dandyoun on this one. If the float is not sticking closed it could be the needle valve it controls may be mostly clogged allowing enough fuel at idle but can't keep up when up to speed.
