Small Engine Troubleshooting Problems? Ask a Mechanic Now.
This is the older flat head engine. DOes it have lots of hours on it? I had one and it started ok, but lost power as it warmed, and would not start hot. The valves had lost all clearance and required the valves to be opened u to .006 inch. Problem is the valves have to be removed and the tips ground off, to get clearance!
