Two stroke oil that leaves NO carbon? ?

I know it's an old thread but anybody think they may have been cutting red concrete or bricks and the air filter allowed he dust into the engine?

It looks like it was cleaned and reassembled right before selling. The cooked underside of the piston shows signs of carbon build up that doesn't match the top.

That engine has seized, from there the color of the exhaust, they have changed piston, that is why it is so clean. That's what I think, I may be wrong.

Engines that make few starts in cold and work longer hot hours, have less carbon accumulation
