It is taken apart already. Everything in the bore measures fine. The new standard sized ring gap measures about .12, spec range in the manual is .10-.20. Maybe rings won't fix it (I hope they will), but you're the one who suggested the rings were the low compression issue, cracked or lost tension. They weren't cracked or broken, so I have to go with they lost tension somehow. The bore is not scored or visibly worn. I have seen worn bores with a ridge at the top and the bottom and everywhere in between is smooth as glass, this has no ridge and still has visible crosshatch in both sides. I've never once claimed to be an expert at this, but I'm not an idiot. It's not like I'm just trying to re-ring an engine that has a severely worn bore.
If everything checks out and it's just bad rings for whatever reason, why does it need bored? I do not understand that statement.
