Piaggio Vespa PX Throttle Tube Return Spring (1984-ONWARDS)
The Throttle Cable return spring is used to help the Throttle tube return correctly. A lot of models like the LML and earlier model Vespa models don't have this part fitted, and only rely on the spring on the Airbox for the cable to return correctly. If your throttle is sticking, always check for dirt and grime in your Headset, also the movement of the throttle arm on your airbox/Carburettor.
