HELP
 
Pull your fuel pumps off the motor. Leave all hoses connected to them. Squeeze the fuel bulb until it is hard and hold the pressure. Check for leaks around the plunger of one or both of the fuel pumps. If one is leaking, you will have to replace it...it is not serviceable.

If no leaks, you could have a stuck float (stuck open) in one or more carburators.

It sounds like it is filling up fast, so my money is on a leaky fuel pump.
