Saw this on a two stroke website....

"Check the maximum wear specs in your service manual. Check the piston for detonation marks in the crown, cracks in the skirt, or seizure marks. Look at the underside of the piston crown for a large black spot. The spot is burnt oil deposits that adhered to the piston because the piston crown temperature was too hot. This is an indication that the carb's main jet needs to be richer."
