What’s the muffler look like? I’ve had one 372 and one 390 do it. I figured either the muffler took a hit or the front bracket holes weren’t slotted quite enough after lowering the cylinder

 

[EFSM]

It looks like the cylinder was ported—is there a chance the base wasn’t flat, or the crankcase for that matter?

Don’t see that very often

Maybe…but it’s broken sideways.

Only had one so far pop it's top, in that case it was from hydro-locking.

Yeah I saw that. Mine were broken on the front. Could’ve taken the same hit from the side though

Water ingestion while running?

Pretty sure Scot said it’s one he ported, was fairly low hour’d saw

At 20 min in he said the owner has had it for quite a while "ported" never did say by whom..

I’m not sure what part of the video it was, but I think Scott said it was one of his saws, meaning he ported it

I didn’t watch the whole vid. Did it have a base gasket or was it bolted straight to the crankcase with sealant? It seems like a gasket would be a bit more forgiving.

"not my saw" is what I heard around 20:20 and "I ported it" near the end.

Get this: the year was 1976 and I had just bought a new chainsaw with a 16" B/C. One of the guys at work heard about it and asked to borrow it. I said OK. He gave it back a week later with a dull chain and a burned out engine (straight gassed). Dealer said it would cost $180 to rebuild it, exactly what I paid for it. I shook my head and said, "I will never loan out another one of my new good saws."

Fuel mix leaked into the crankcase from a leaking needle and seat in the carburetor, it fired up and next revolution went pop.
