It is likely a float or float valve problem - sometimes the float gets a 
hole in it and sinks, but other times something sticks and keeps the 
valve from closing. I would take the top off the carburetor and take a 
look. If the float is leaking, it will be full of gasoline. You need to 
get the gas out and find the hole (by dunking it in a container of near 
boiling water - there will be air bubbles coming out at the hole). Once 
you locate the hole(s), you can either try to solder them over or simply 
cover them with a thin layer of epoxy (such as JB Weld). The epoxy 
treatment is much easier for me. If there is crud in the gas that got 
caught in the float valve, that can be cleared. Very old valves can 
benefit from being replaced - the needle and seat actually do get worn 
over time. Also, look for binding in the movement of the float - if the 
gas in the carburetor dries out, it can leave a "varnish" that prevents 
the float from moving on the hinge pin. Some shots of spray carburetor 
cleaner into the guts can work miracles sometimes.
