What does all this sign on the piston mean? I got to looking at it today through spark plug hole and cylinder looked so I good I took and turned the flywheel backwards just a tad and it came loose. Poured some 2 stroke oil in and started slowly pulling the rope and it got free. Popped compression test and it was 90, so I pulled the jug when I got home and this is what I found. I believe I can clean up the ring groove and put it back together if it won’t hurt anything for now, to be sure everything else is operational. If crank is good (which it seems to be good and tight, but when the piston gets to TDC there seems to be a slight bind or something when you turn it slow, but when it’s pulled faster its not really noticeable) and everything checks out good, I’ll buy a new piston and all and go ahead and get her wood ready. Just wanted t hear some thought before I do that
