HELP! 66 corvette fuel problem

[67l78]

Hope some one can help with this.
My vette has not been fired in 4 or 5 months. I fired it up today and it was smoking like a freight train. It was not smoking when I parked it.
It was however spewing a little fuel from the carb when I shut it down last fall/winter.
I was able to back it out of the garage(befor dieing of c/o poisioning) and smoke was pouring from the side pipes(again, It did not do this when I parked it) It wouldnt clear up so I shut it down. I lifted the hood and could see what looked like dirty fuel (was for sure fuel,but looked just a little oily) all over the top of the fuel pump and a little laying in the intake manifold at the base of the factory holley carb. I also noticed some on top of the right side exhaust manifold, thought maybe the fan blew it up there??
When I could finally enter the garage again, there was a small puddle of the same dirty fuel on the floor just below where the fuel pump would have been and a drip pattern where I had backed out.
I also pulled the dipstick and it smelled strong of fuel.
Is fuel some how still flowing into the motor after it is shut off? It seems to me that it is or was. The throttle linkage is not hung open or anything. I have never had a problem like this. Does the carb need rebuilt and the fuel pump replaced? Could this have damaged the motor some how? It was not knocking or anyhting like that. I probably only had it running for 3 or 4 minutes, and I pushed it back in the garage.
What do I do?? Thanks everyone!!
