I am not sure that the nozzle gasket area was the problem. It sound like the vent in your original carb was blocked. Once the fuel gets high enough in the bowl, the float seals and that is where you get the primer pressure from. The nozzle gasket is there only to make small motors respond better to the high speed needle adjustment. The fuel inside the cavity for the high speed jet is at the same level as the fuel in the bowl when the engine is not running.

If the vent is blocked, the fuel level in the bowl does not rise enough to seal the float. I hve been down this road, and it drove me nuts.
