    There was no nozzle gasket on those motors from the factory. The smaller motors had one to ensure that all of the fuel has to pass through the high speed jet. You can add a gasket, it will just make the high speed adjustment more sensitive. I often add it when I have one in a kit. I don’t have a part number handy. The gasket was in the kits for later engines.
