Right now my question is what caused the appearance on the piston?? The mechanic says the problem is the gas and the carb and that's why he was referred to me. But I disagree that a carb problem would cause a vibration. Maybe a miss or hesitation, but not an actual vibration.
I'll be speaking with him later for more info.

He just sent this pic of a plug. They all look like this and they look fine to me.

Agree. I was thinking detonation due to an extreme lean condition, but the plugs show otherwise.
