Never had any issues boring one and putting oversize rings and piston in. A hardened aluminum block? I've never seen one, all I ever saw were the aluminum bore blocks and the steel sleeved aluminum blocks. Yours isn't like some motorcycle blocks and has a chrome or nikasil plated cylinder does it?

You can scratch the outside of a new engine pretty easy with a screw driver, but it takes a bit more pressure on the cylinder wall. Similar to tempering steel. It seems to me that oversize rings are made of a softer material than standard when it comes to aluminum block engines. I know what you mean about the nikasil. My sled has it. My Briggs is a 74, so nothing so fancy. Perhaps I will take her to the engine machine shop. It's not a restoration thing like my Ferguson, it's just me being cheap. But the less money I spent on the blower, the more I have for my TEA20. [Reply]  [No Email]

If they are still available for it. I would think that they are. [Reply]  [No Email]
