Main Jet #49 for Vespa Small Frame and PHBG Carbs
This main jet is made for Vespa small frame scooters that use 16mm and 19mm carburetors. It controls how much fuel reaches the engine, which plays a key role in how the motor runs. Among the scooter carburetors & jets we carry, this part is one of the main tools for adjusting the fuel mixture. It also works with PHBG carburetors, so it can suit more than one setup.
Jet Specifications
Main jets come in several sizes, and this one is the 49 size. On small frame Vespas, the main jet operates together with the idle jet to control how the engine runs. Dialing in jets usually takes some testing and adjustment, so patience and a careful, step-by-step approach will help you get the result you want.
Installation and Fitment
This main jet sits inside the carburetor and replaces the existing jet. The job is simple enough for a home mechanic who wants to work on their scooter's performance.
