The cylinder was in good shape, and still had sufficient cross hatching. I did remove the cylinder and piston from the engine to replace the piston rings.









After removing the cylinder I cleaned it with a scotchbrite pad and ATF. I soaked the piston for 24 hours in a gallon can of carburetor cleaner to remove the carbon.

After the piston was cleaned, washed, and dried, I installed new piston rings. I compressed the piston rings by hand and installed the piston into the cylinder before I installed the cylinder onto the engine block.

Tilting the engine to one side, I partially lowered the cylinder and piston until I could install the piston pin and piston circlip. After pushing the piston upward into the cylinder, I lowered the cylinder onto the engine block.
