Carburetor Box Mixture Screw Rubber Plug - Largeframe Vespa

Carburetor Mixture Screw Plug for Largeframe Vespas Built After 1958

This rubber plug fits the mixture screw opening on the carburetor of largeframe Vespas made after 1958, with the exception of GS and SS models. Its job is to keep that mixture screw access point closed off and guarded. Like many vintage Vespa scooter parts, it sits straight into position, so swapping out a worn or broken plug is simple. Keeping this plug in good condition helps the carburetor run cleanly and hold the correct mixture.

Construction and Design

Made from tough black rubber, this plug has a flat round flange, a raised donut-shaped ring in the middle, and an open center hole. The panel grommet design seals the carburetor box so dirt and debris stay out. It is an OEM-quality replacement, built to match the original fit and function.

When to Replace

Think about replacing the mixture screw plug if it shows wear, such as cracks or a loss of flexibility. A damaged plug can allow contaminants into the carburetor, which can hurt engine performance. Checking this part now and then can help your vintage Vespa parts last longer.
