That's the way most pistons are manufactured.
Not the piston, the cylinder.

Oooops!Not the piston, the cylinder.
Are You Still taking about this saw?It was 4 stroking so hard outta the cut I thought it was 6 stroking
+ "I have a potty mouth"
The saw never seized up.I am going to say this one was a cold seize. If most of the scuffing occurred where the piston has the most mass such as the webbing, points in the cold seize direction.

And I let it warm up before any WOT cuts were made
Good,..then the piston expanded just as it it is intended to do, but it swelled too quickly, the cylinder did not expand as quickly as the piston did. The skirts are always larger in dia than the crown but the whole piston expands so the skirt would actually be tighter in the cylinder for just a couple of seconds byt enough for it to scuff itself badly. IMO.
Cold seize happens very early. Right after startup.
But the saw was warm.... Think shrinkage.
Most of your pics aren't showing. Is it just me?
