There are a lot of clutch removal threads here on AS - I would have posted this experience in one of them if I could have found a 'main' one. Most of the threads describe three ways to stop the piston for clutch removal:
- commercial piston stop;
- rope stuffed through the spark plug hole;
- use of an air-impact wrench.
I am cleaning up an older, STIHL 024AV Super, that is in really nice shape, so I decided to 'do it right' and use the STIHL OEM/factory piston stop. The muffler was still on, and I guess that I did not get the end far enough into the exhaust port (or maybe the end was too large to fit?). The piston stop slipped and the clutch did not move, so I used the rope trick and got it off.
But something did not feel right, and the piston stop looked a little rough at one end, so I pulled the muller and found what is shown in the photo below inside the muffler. Feel better now that I got what looks to be all of the 'extra' parts out, but I feel a whole less confident in the OEM piston stop right now!
