Robert,
it sounds as though one of your float needles has stuck and a carb float
bowl is overflowing. I have become something of an expert on this as my
fuel gauge doesn't work and I keep running out of fuel. When this
happens the float in the front carb sticks in the down position so that
when I fill up the pump runs and runs and...pumps fuel all over the
place. After much disassembling of carbs I found out that a few whacks
with a solid object to the offending float bowl gets the float floating
again. By the way the carb overflow lines connect together and then are
connected to the carbon canister, (which you probably don't have).
Good luck,
Simon
