Vespa LF Idle Screw Spring

Idle Screw Spring for Large Frame Vespas

This idle screw spring is made for the carburetor on large frame Vespas and is meant to keep idling steady. It suits every large frame model apart from VL1-VB1, VGL1, VS1-5, VSB, and VSC. Like other Vespa scooter parts, it installs directly in the spot the original occupied.

What This Part Does

This spring helps control the idle speed of your scooter. On some models it also returns the throttle slide, while on others it serves as the throttle stop screw spring. Swapping in a new one can help your scooter run more smoothly.
