Carter AFB 625 Overflowing with fuel

My 1978 Ford Bronco had been sitting for several months and one day I went to start it and it stumbled and died. I popped the hood and fuel was spilling out of the carb onto the intake. I intially thought the fuel had gummed up in the carb so I bought a rebuild kit, disassembled it, soaked it in carb cleaner and put it back together. Now, this was my first rebuild but it seemed to go back together fine... I went to start it and it started ran for a second and then died again. Once again fuel was all over the carb, intake and dripping from the nozzles. Any advice???? I dont claim to be a carb expert by any means but I thought the floats were stuck open. Thanks!

I don't know much about carbs either, so for what ever it's worth....

The floats allow fuel to enter the carb by opening up a needle seat, right? And you did check that. The only other thing I can think is that there is some kind of vaccum being created in the carb which is pushing or drawling the fuel up into the throat. I have seen where spiders build webs or other things in an area like a vent tube. Do you have a vent tube that might be clogged with something?

Sorry bro, that's all I got right now!

Imagine life with no paved roadways!
