Well, I haven't noticed any black smoke other than just a bit on startup. My plugs have a tendency to be black, but haven't given me fouling trouble.
There may be other symptoms, but I'm not sure that I've noticed anything else.

Sometimes it is hard to discern between lean and rich conditions. What are the other symptoms? Black smoke? Black plugs?

I agree, Bruce, it seems backwards to the symptoms I'm experiencing.

Greg, I'd think that a higher pressure in the gas tank would lead to fuel being pressurized. Maybe to the extent that it "overpowers" the float and you get an over rich mixture.
If you get a vacuum in the tank, then you get fuel starvation; this condition seems just the opposite.
