[FONT=Comic Sans MS]I can't get my Craftsman 5 hp to start. When I pull the starter cord it goes through one complete revolution and then seizes and won't go beyond. When I take out the plug, the starter cord pulls as if normal. I think it has something to do with compression but beyond that I draw a blank. Could the exhaust valve have seized up? Timing?[

I ran it low on oil recently , could this have something to do with it?

Any ideas what I might do?
