First method: (creator: Generic) 1) Remove the cylinder head. 2) Spray piston and cylinder walls withh PB Blaster. 3) Use a sledge hammer and a 2 inch wooden dowel to wack that sucker loose.

Second Method: (Creator: Eric P) Try this method only if the cylinder is stuck tight and the ports are closed off. 1) Take an old spark plug and cut the top off with a hack saw or dremel (all of the yellow parts in the picture).

The grease gun will generate a lot of pressure which will break the piston loose. Good luck! -Eric
