There's only a few possibilities:<br />1) Needle and seat leaking. These shut off the flow of gas to the carb when it fills. The needle should look like a perfect taper. They cost about $5.<br />2) Float has sunk. If it's an old cork float, it could be saturated. Try putting the float in gas and see if it still does. ~$10 for a new one, I think.<br />3) Float is getting stuck. It may be hitting the side of the carb, or getting hung up on the gasket. Try tapping the side of the carb.<br />4) Float level is *way* out of adjustment. It should be adjusted so that is level with the carb bowl mating surface when the carb is turned upside down.<br />Hope this helps!
