Remove fuel hose & top cover bolts
Use your 12mm socket wrench to remove the starter, be careful not to lose the rubber seal located on the underside of the starter.
Next, remove the head by loosening the four 12mm bolts. The head may be stuck tight due to the head gasket. Gently pry the head away until it pops off.
If there is no head gasket, or you suspect that the head gasket wasn’t sealing properly, you could try to replace the head gasket before replacing the piston and rings. The piston can be inspected by looking through the exhaust port to see if damage has been caused due to carbon build-up.
Next, stuff the cylinder with the small rag and gently place the head on. This rag will stop the piston moving, allowing you to undo the crank pin.
Use your locking pliers to grip the crank pin and the use your adjustable wrench to loosen (remember left to loosen), or, if you have the other crank pin use a screw driver and hammer to loosen.
Now remove the head and take the rag out of the bore. Spray some WD-40 and push the piston out of the cylinder from inside the crankcase.
