Jet, Idle #45 - SHA/SHB for Scooters & Mopeds

Idle Jet #45 for Vespa Scooters and Mopeds

The Idle Jet #45 is made for Vespa scooters and mopeds, and it suits models such as the Primavera and ET3. It adjusts the air-fuel blend inside the carburetor, which plays a major role in how the engine runs. You'll find it among the carburetor and jet options for scooters, where it can help with starting and idle problems. If your Vespa bogs down or surges, this jet may be the fix you need.

What This Part Does

At low engine speeds, this idle jet controls how much fuel flows through, which keeps running smooth. When the jet wears down or gets blocked, hard starts and weak performance can follow. Installing a new one can bring the carburetor back to proper working order.
