This evening I gapped all the rings and installed them on their respective pistons. It sounds like a five minute job but it took well over an hour.
I gapped all the rings to .018-.020 per the specs on the paper that came with the rings. I'm using Deves, which have a bottom "scraper" on the middle ring to help keep oil out of the cylinder. It's important to keep the scraper faceing down or it could work the other way and push oil up the cylinder wall.
Next up is the installation of the pistons, and possibly the crank.
