It's the high g-forces pushing the fuel in the tank back aginst the rear of
the tank and out the filler. Not buying that, huh?
I think that the function of the float valves is to shut off fuel supply
when the floats are full. Unless you have an electric pump that is pushing
at more than 4 lbs, it shouldn't be able to overfill the carbs unless the
float valves aren't working or the floats themselves are messed up. I think
that's where I would start looking for problems.
