To remove the piston and sleeve.
Clean the outside of the engine with a brush so nothing gets in while you have it apart.
Remove the head (watch for shims too) and the various backplates until you can see the engine's internals. (might be 1, not sure if there's a pull start or what on there too)
Fold a thick zip tie in half. Put it in the exhaust port with the piston at BDC (bottom).
Turn the flywheel by hand. The piston should push into the zip tie, pushing the sleeve up.
Carefully go around the sleeve with a flathead and pry it up GENTLY.
Now take a pair of non toothed pliers or pliers with a rag around them and pull on the connecting rod. Note the direction of the piston in the case.
Now take off the clutch. You can do this 2 ways;
A-Clutch shoe remover
B-Flathead screwdrivers
A is the easiest for the 3 shoe clutches but I'll bet $20 you don't have one, so...
B-Take a flathead and pry up the shoe from the front of the engine. Take another one and push the shoe away from the flywheel. It should slide with some pressure. Watch out for the spring, it might shoot off but I've never had that happen. Do that to all 3 shoes. Then take an old screwdriver with a plasic handle and hit the flywheel from the back to pop it off of the crankshaft. Remove the (usually) brass cone and you're done.
