    …..the lower piston face would be covered with a coating of carbon

    interesting…. I will inspect closely thanks for heads up

    now that you folks mention it I think I did see some oxide

    I will let you folks know if I find anything suspect but I seem to remember changing the exhaust cover plate to stainless. maybe a bad gasket …
