I have some black oil coming out of my muffler on rebuilt MS260 was reading some of the threads here on it seems many say it could be from the case gasket in the oil tank area gone bad. If it was the case gasket would it hold pressure and vacuum? My saw holds pressure and vacuum perfectly. This saw has a new top end on it and I have so far only run it for maybe 15 minutes could it be that it has not seated in yet causing this? It seems to run real good but if I have the carb to rich would this pump oil out the muffler?
It is not flooding out or anything it starts easy just a few pulls when cold usually 2 pulls on full choke then 1 pull on 1/2 choke.
