Rich is going to hurt parts.
What's the wide band say?
Where's the timing at. Looks like it's hi and the hole is fat. That hurts more stuff then lean and no timing.
What he said.
Rich is not safe. Pistons burned to the ringland always happen closest to the intake valve. Rich and advanced cause exactly what you see there. Back off the timing significantly, lean it out slightly, and read plugs to sneak up on it. When the plugs look good back the timing down 1 or 2 degrees for a margin of safety. It will cost you some power... but the durability is worth it in my eyes.
