Vespa LF Choke Valve Screw

Choke Valve Screw for Large Frame Vespa Models

This choke valve screw holds the choke valve in place on a range of large frame Vespa scooters with a manual transmission. On VS1-5 models, it also secures the float chamber cover. Because the carburetor depends on it, this is one of the Vespa scooter parts that may need swapping out during routine upkeep.

What This Part Does

The choke valve screw supports control of the air-fuel mixture the carburetor sends to the engine. If the screw is worn or failing, you may notice symptoms such as difficult starting or rough idling, which suggest it is time for a new one.
