Back in the garage and it feels great
Look what came yesterday:
I began installing them this afternoon when a question popped up. On the packet it says to instal rings with the marked side facing up (both compression rings have a "T" stamped on them, no "R's" to speak of) so I did that, but the two compression rings themselves are noticeably different. One is all black and is more "expanded," and the other has a silver coating on the outside and is more closed. I figured the all black one would be the top ring as it will have the most compression force, explaining why its slightly more open when uninstalled. Do you guys buy that?
Also, I re-honed the cylinder with the scratches in it. After a few more passes the scratches are visible but I can't really feel them with my fingernail so I'm going to say it's ok. Measurement of the new rings after the hone is impressive with 0.3mm end gap!
