I need a-little advice. I've written enya-engine.com twice and didn't get my usual immediate response from Ken Enya. I just bought and rebuilt an Enya .46-4C. The ring endgap is .011" or .279mm. It seems excessive to me. Any guesses as to what is acceptable? In addition, does anyone know the where abouts of a gentleman that specializes in piston ring sales and, I think, manufacture that is mentioned many times in posts here.

Thanks,
Bill
