you mentioned that the car sat up for 12 years - did you drain and remove the fuel tank? my "37 had been sitting up for 15 years- I removed 3 pounds of rust before having the tank repaired and sealed. It does not take much rust to get into the seat of the needle valve and to result in a flooded carb - you mentioned fuel coming out of the bowl.
MY '34 Rolls 20/25 has an Auto Vac - if you choose to install one on your car make sure that the fuel supply line stays as far away as possible from the exhaust pipe as well as your gravity line down to the carb float bowl. Vapor lock can be a problem - heat combined with the suction pressure causes the fuel to vaporize in the supply line to the vacuum tank. Locating the Auto Vac on the firewall of a hot engine compartment seems to be a poor design to me - hope your hood is ventilated. Keep in mind that the addition of ethanol to fuel makes the EPA happier because the fuel burns hotter, ie exhaust pipes.
