Some rings will take a bit of abuse before they snap and some won't. I don't know if the quality of the rings has anything to do with it but I wouldn't bet against it.

Right. I'm not sure OEM is always the best in this respect. I've accidentally abused the AM ones and not had them break and I've had them and others break easily. It might be an individual thing. I've worked in mass production and although the product all looks alike sometimes they don't all function the same. Rings are supposed to give a little before they break otherwise they wouldn't work in the engine nor could you compress them.I'm not sure, I bought a new oem stihl piston for a ms170 and I tried to put in the cylinder using the taper to compress the rings and the top ring broke with no force.

Make sure the ring will fit the locating pin of the piston. Some rings are cut to ride on a certain side. If you miss this step, the ring will not compress far enough to fit in the cylinder. The other thing is cut yourself a one inch wide by six inch long strip of ring compressor from an old two liter pop bottle. Oil it and slide it in. Dont twist the jug.
Dude you gotta clean that cylinder upI got the new ring on the piston, it went on very easily with the wrap method and covered in oil. I was about to try to put the piston back in and got to looking at the cylinder wall again. I have read about the acid removal method, do you guys think it needs it. I dont have the acid but I guess I could find it somewhere. I can barely feel the aluminum when I pass my fingers over, but I can feel it.

Actually, you can sand through it.You can't hurt the nikisil with sandpaper. Get back in there.

Man, this stuff is so confusing to us mortals I've read on some sites including this one that this is way overkill and others say it's the best way to clean it up. Emory cloth is the best way and now I hear it can eat through the cylinder. I think I'm finally understanding that every process has multiple ways to achieve the end-goal, but common sense and a little critical thinking is the one similarity that is found within all of the processes. That and s#!+loads of trial and error.I use a break hone to prepare cylinder before installing piston. Also rinse it out thoroughly and blow it dry.
