<VV> venturi fuel drip

[Edmonds]

After receiving such great advise on the starting problem on my '63 
Monza I was able to get the engine going but noticed after the engine is 
shut down, looking down the carb venture on the right carb I see gas 
continuing to drip for several minutes.  I pulled the carb apart but did 
not see anything out of the normal.  Would this possibly be due to the 
float sticking or a faulty needle valve?
Thanks once again.
