      Disconnect the fuel line from the carb. Put a hose on it and put it in a container and turn the engine over and see if the pump will pump.
      If the fuel filter in the carb inlet, or the needle valve is plugged, it will not pump gas into the carb or to it.

        i agree with don, however you stated no fuel is moving through the lines?? so possibly the anti syphon valve ( if equipped) could be stuck on the fuel tank as well. take off the hose from the tank and spray some carb cleaner into the fitting 2 quick shots the ball should move freely good luck!!
