Tore apart a couple of trashed Stihls, the piston of an ms230 on the left, 250 on the right.
Both saws had main bearing failures, and had ingested pieces of the bearing cage. Both ran in this condition and hammered the pieces into the top of the cylinder.
Of course both pairs of pistons/cylinders are junk, which is a shame as the scoring on the cylinder walls is minimal.
