Me and my buddy have been discussing about installing a steel sleeve in the cylinder, by doing some machine work to make this engine dependable for a long time. Stronger rings and piston. With no mysterious metal shavings appearing in the engine. He is a master journyman grinder at a factory where i work and it can be done. It won't cost me a dime. So i am going to go ahead and do it. He just wants the cylnder to start it. We are going to order the piston and rings before we do it to get the correct dimentions. Cross your fingers and i Will post pics when completed. hopefully no more scarred cylinder and no more destroyed pistons, and everlasting compression.
