I can ask for a pic of the plugs. He said the vibration starts at about 1200rpm and gets worst up to about 35-40mph. He can feel it in the seat and it's bad. He said all the normal suspects have been checked, ie: tire balance, driveshaft, pulleys. The mechanic said he checked the crank and its good.
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.
