Carburetor loses prime after 8+ hours

Holy crap! I stopped getting notifications about responses to this thread LOL.
Well, I have a holley red pump to go in it, as well as a regulator, which per the instructions for the pump I dont need, but it was already ordered by the time I realized that, so it will get it anyway, no big deal.

I still have to install it. The car runs and drives great other than the hard start. I havent driven it in about 2 month until the other night. It took a few primes to get it started, so the problem is certainly getting worse. I actually think you guys are right about the carburetor. It seems to be leaking into the engine because it is a bit flooded on restarts after a 10 min or so pitstop. A reman might not be such a bad idea even along with the fuel pump, idk.
