Look at the big hole where the air enters the carb (choke end). See the large hole (or holes) beside it? That hole goes in and intersects with another hole that leads down into the float bowl area. That is the vent that allows the air to escape as the fuel rises in the bowl. If the air cannot escape, the fuel won’t rise and if the fuel (and float) does not rise, it won’t shut off the inlet needle. If the fuel rather just keeps pouring in, it overflows out the main nozzle.

I don’t know if your nozzle gasket is sealing or not, but in any case that won’t cause the overflow.
