    quote need2fish:

    Pits will not hone out. Anything larger than the width of a ring will cause compressed fuel to leak by the ring. You can,however, ignore pits beyond the travel of the rings.

    IMHO only cure for pits (as opposed to surface rust), is to bore out the cylinders. Unfortunately, I’ve never seen oversize pistons for a Mate (doesn’t mean they don’t exist).

    Q: What did you squirt in the sparkplug hole, raw gas or mixed ? Raw gas won’t seal as well as fuel mix.

    BTW there is a guy selling the .030 oversize rings and piston on eBay right now for $25usd. Very rare but they are out there. Just an FYI lol.
