Ok guys, on my second flight today my O.S. 50sx sputtered and died. I found out that I had enough fuel so I checked the plug and it was gone. So I replaced the plug and tried to start it up again and noticed it was making a horrible clanking sound. It also seemed to have much less compression than normal. I was using an electric starter so it turned over a few times[]

I got it home and took it apart and this is what I found. I thought at first it was the element from the glow plug, but I don't think that could do that much damage could it? What could have caused all this? I took the whole thing apart and never found the culprit.........[sm=confused.gif] The piston sleeve and everything else seems to be ok. The connecting rod also has a couple of nicks in the outside of the ring.

Can I just replace the piston, head, and ring?


(and no, I don't have a fuel filter on this plane)
