    Hi,
    Something is going on that does allow the float/needle combo to shut off fuel flow. The fuel is coming out the bowl vent, which is necessary to make the carb work. Should probably be coming out of the slanted brass tube in the throat of the carb at a rate more than normal too.
    My guess is a piece of trash caught (and missed) in the seat.
    Peace,
    Clarke
