How long did it run before the damage occurred? I would have expected to see a lot more piston damage. I see the damage to the cylinder port - that is the intake port, right? Looks like something was sucked into the intake.

Had run the saw for 1/2 hour, maybe. It quit and when I tried to start it I felt it catch and then would not budge. In hindsight, I wished I had taken the carb and exhaust off first. Muscled the head off which explains the damage to the intake port.
