I've rebuilt a few in my time: That CF poster has a flooding situation that has nothing to do with Sta-Bil (that won't hurt a thing in the tank full time); sounds like a stuck float or crudded up needle valve. But yes, if the car has sat for an extended period - like several months; the internals can certainly gum up.
Sometimes, a sharp rap on the side of the fuel bowl with the plastic handle of a screwdriver will loosen up a stuck float. Its also worth checking the fuel pump pressure, anything over about 5 lbs will force the needle valve off the seat and flood the carb.
