I attempted to start the car today. Nothing...no gas squirting either. I go take the hose off the carb and gas starts spraying out - there was built up pressure.

I took the top of the carb off and it seems that the needle and seat is sticking. When the float drops, sometimes the needle stays in there. If I blow into the gas port, air only blows out of the other side/float. The needle on the side closest to the drivers side stays in there.

I rebuilt this carb 2 years ago with a Pep Boys carb kit. I just ordered a new Borg Warner kit with new needles/seats.

I don't understand how its sticking - clean as a whistle and not much use at all - no visible wear. Maybe the carb kit was cheap...
