Main Jet #48 for Small Frame Vespas and PHBG Carbs
This main jet is made for small frame Vespa scooters that use 16mm and 19mm carburetors. It controls how much fuel flows through the carb during operation. It also works with PHBG carburetors, so it suits anyone servicing scooter carburetors & jets. Getting the jetting right can help performance, and this part plays a key role in tuning your scooter's engine.
What the Jet Sizes Mean
Main jets come in a range of sizes, from 37 up to 88. This jet, #48, is the size meant for small frame Vespa scooters. The needle runs through the main jet, so it has a direct effect on how fuel is delivered overall.
Fitting and Tuning
To swap the main jet, take out the current one and fit the new one in its place. Finding the right jetting often takes some testing. For guidance on adjusting jetting to suit your scooter, check the available reference materials.
