I may getting a step ahead if Bill, but here goes anyway.
A set (four) pistons and rings and a new full gasket set have been ordered from Snyder's. It was easier to order set than try to match the one odd one. We will scrape the light carbon from the top of each cylinder and then run hone lightly thru each cylinder. ...and yep I will take my cylinder gages and check the diameter top and bot of each.

jfreddie. The oil ring was not the problem. It was jammed due to the scraping of the aluminum and the Al depositing itself into the oil ring groove on the piston , seizing the ring into its groove. clear as mud? ken
