Teardown: complete

Well, taking the engine out of the bike and getting the top end off goes a lot quicker when you have some motivation. My findings so far: the piston rings were in fact in the wrong order (the correct order is square profile first, then stepped profile, then thicker oil scraper; I had the square and stepped rings swapped); the combustion chambers were positively swimming in oil, far more than I had expected to be there; the oil didn't seem to be coming from the valves, or at least not much; still nothing that should be making that clunking, rattling sound at idle; oil all over the engine is from the points cover gasket not sealing.

It was nice, at least, to get the engine torn down enough to confirm that I'd done the rings wrong. I can probably get it corrected, cleaned up, and back together this weekend, assuming nothing goes wrong. Hopefully, that's not a big assumption.

I have discovered (well, more confirmed, I guess) that Orbital is excellent engine tear-down music. I'm sure you were dying to know that.
