Widget, pull the carby off, remove the float bowl and then you can get at the needle to see if anything is visibly wrong. You can test the needle with the bowl removed by hooking up a fuel bottle to the inlet on the valve, shut it open it to see if it actually shuts the fuel off, then with the fuel switched on fuel should flow and by lifting the float fuel should stop flowing. This is the principle as to how it works
