It’s pretty rare…maybe never….that I have taken apart a 20 to 22 cube two stroke engine of ANYBODY’S manufacture, that there hasn’t been a least a little scoring of rings and pistons. Yeah, yeah, I know what they say; but if the scoring is light on the pistons, I gently clean them up, reuse them with new rings and always have had good results. (Heck, some of these guys will break free a seized-up engine and run it. Usually in those engines, the rings aren’t just scored, they’re STUCK.) As for the sealant, I like the anaerobic kind. I have tried Yamabond, which is probably like the Honda stuff (Gray?) and have noticed that it really doesn’t totally resist ethanol fuel. It’s great on four strokes but I personally wouldn’t trust it on the crankcase of a two-stroke. Just my opinion, on both subjects.
Long live American manufacturing!
