Like the title says - what are the symptoms of float levels being set too high?

Judging by what I went through......running too rich at idle, fouling plugs when running around town. The bike ran pretty good at higher revs, but sputtered a bit off of idle.

Burbling when cruising, flat spot when opening throttle, black plugs, poor mileage.

+3 on the above comments except that gas doesn't always come out the overflow. I knew my bike's floats were "off" when I would be riding it and turn off the petcock and the bike would immediately smooth out and run like a much different beast.

+1 
1mm in float height can make a big difference inside the bowl. 

your original question was about float levels being to high. 
floats set too high, or set so that fuel levels are too high?
please clarify as they are opposites. 
we've all assumed you meant the fuel level was too high based on our answers ::)

Sometimes if the levels are too high, gas can go in the intakes
and airbox. It can occur very slowly and cause a no start condition.
Sometimes it can be bad enough to the point that the execess
fuel dilutes the engine oil, which obviously aint good either.
Best to use the clear tube method when checking actual fuel
height in the bowls....and +1 on whats already been mentioned.
