Don't know what happened here guys, could use some help. It was about 0 deg C out that day so pretty warm, sled has run in -20 this season already. Sounded like a plug starting to foul then eventually lost the cylinder completely. Here are a few pictures of what happened. Does the wash look ok or is it too lean? It doesn't look like there is any melting of the piston but it's hard to tell.
