Combustion chamber looks fresh, was this a current rebuild? Brand? Tolerances too tight?

Dammit I call clickbait. You made it sound like a contest.

I guess he shouldn't have started it and stuffed it in wood at wot on a cold day.

Cold Seize. Stihl has always had problems with this. The early 066s were notorious for it; there was something like a 30 percent failure rate.

 

[Brush Ape]

The cold seize with Stihls was actually determined to be trigger mortis. And it was particularly bad with the older pro saws. Try prying my cold dead hands off of it.

Always best to warm up those large jugs first.

Looks like classic 4 corner to me. Haven't actually seen many saws donit though, mostly just sleds.
