Guest VeloMan Posted January 10, 2008 Share Posted January 10, 2008 Are there any shops specializing in vintage 2-cycle engine restoration, or will a regular engine rebuilder do this? Link to comment Share on other sites More sharing options...
Mark Shaw Posted January 20, 2008 Share Posted January 20, 2008 You might try an outboard motor shop. Link to comment Share on other sites More sharing options...
jfcpeng Posted March 7, 2008 Share Posted March 7, 2008 What sort of two stroke is it? Is it a humped cast iron piston? Just find out the existing ring gap and the piston clearance. It is often cheapest and easiest to resleeve the barrel down to the existing piston with new rings. The ring gap is very imporatnt on two strokes, as is the correct piston clearance at the crown and skirt. If it is air cooled, be guarded talking to outboard people. It usually pays (especially say a racing engine) to run the motor to warm to hot, strip it and rehone it to reduce high spot seizures. Make sure rings are free to move as rings do most of the work! They usually seize/tighten above exhaust port. Do not use synthetic oils! Link to comment Share on other sites More sharing options...
