farther and far into this 1200 I find crazier things so one power valves pin fell out and was tapping on the top of the piston shaved most of the power valve it doesn’t look like did very much damage to the piston there’s just a sharp lip around the edge where the power valve was hitting should I file the piston or go new? On another power valve was extremely dirty and it look like it had damage to it, I don’t see any piston damage. So I have some pictures of the parts. And why does one of the power valves have a different bushing?
