Hi, I just picked up a really nice 051 Stihl, all original and runs real good. The problem is when it sits unused for a while Oil from the chain oil tank finds it way into the crankcase and past the piston, and locks the engine, remove the spark plug, drain it out and it starts and runs fine. Seems to run too good to be a blown case gasket. Has anyone encountered a case where the oil pump or some seal can do this???? I talked to a guy that had the same problem on an 075, He said he just stored it with the bar pointing down and never looked for the problem. This is such a nice old saw, I want to fix it right. Any suggestions ????? Thanks/379 Pete
