I am just about to go crazy. The short story is that i have already ruined a perfectly good saw by cramming a rope into the Cylinder to remove the clutch and I am preparing to do it again. If I put just a little rope in the thing, the saw will still revolve 360. If I cram enough into the cylinder that it will not move, then I end up getting it caught in the exhaust or other port and really @#$ing it up. I just did it again, but may not have ruined the saw... YET.. I got too much rope in the thing, got it caught in the exhaust port, flipped the entire saw onto the ground and thought I had broke the case. Didn't break the case but could not move the crank either direction because I had the rope jammed in the exhaust port. So what do "I" do??? I try VERY carefully to turn the crank backwards with a screwdriver and break a fin off!!! @#@$!!! How else? Can't I just stick a wooden down into the exhaust port with the muffler removed?
