One thing that comes to mind with the Stihl Clamshell saws  (MS 210-250 & 290, 310, & 390) There are smaller saws too. The problem is the bottom cover or pan coming loose after re-assembly of the engine unit into the plastic outer case.

The solution is partially covered in the first post of this thread but to carry through with the solution, In addition to new seals, it talked about cleaning and leveling the mating surfaces and using a sealer like Dirko or Three Bond sealer on them (not PVC). It has also been mentioned to bolt the cover down outside the saw. This is considered important.

Then let the engine unit set on the table until the next day all bolted up before you touch it again. This is an attempt to let the gasket sealer set up.

Then carefully remove the bolts and place the engine unit in the plastic housing and re-install and torque the bolts from underneath the housing. Try not to bump the engine unit or do anything that would loosen the pan while placing the engine in the plastic case or installing the retaining bolts.
We should share what we know... someone may learn...
That knowledge can live after us... and that "Pays It Forward".
Be all that you can be . . .
