Oil on pistons?

Rat Bastid said

You need to STOP running that engine and get your carb and timing squared away.

That thing is disgustingly rich.

I don’t know what carb you have but it needs work. A lot of work.

The last thing you need to worry about is the oil on the piston tops. You need to worry about WHY the oil is there and that‘s your carb tune.

I agree that plug looks extremely rich especially after only 1 hr of running. What I don't know is whether oil intrusion into the cylinder can cause a plug to look like that after only 1 hr of run time. What you think? I still think he has oil being sucked into the cylinder whether it be from bad intake manifold seal, blown head gasket, valve seals, rings or whatever else. I think that amount of oil after shutdown is unusual. I am curious whether all cylinders show that oil.
