Usually, I take a piece of rope instead, but the convenient one was covered with steel dust from the angle grinder, so

It was the ms201T and I used the stopper supplied by Stihl with the saw. Maybe not too bad.
It seems to go into the squish area, so the piston isn't far from the top dead center. That's effectively a concern, as the leverage on the crank and the connecting rod is as bad as it can be. It would be much more favorable at the halfway mark.
I did destroy a connecting rod on my 021 ( stupid cheap part, just stamped in a sheet of steel). I folded it in a U shape because I manly tried to unscrew the clutch the wrong way.
