A:

I show only rings/piston for standard size and for .020 (pt 499292) over are available for this engine. At one time there was a .010 and .030 over kit but those have gone out of production. I don't think you'll be able to work with what you have on this as the cylinder is just too worn.

Thank you for using Manage My Life!
