Last summer I serviced a similar machine and found the screen for the incoming cooling air almost completely blocked. The cylinder cooling fins were about half filled with crud. As the fuel hose passes close thru the blower housing, you may be getting vapor lock in the fuel line from engine heat. Remove the recoil starter and check the screen.
