It controls fuel delivery, which has a direct effect on how the vehicle performs. It belongs to the \u003ca href=\"\/collections\/scooter-carburetors\"\u003escooter carburetors \u0026amp; jets\u003c\/a\u003e range, since these parts directly shape how well the engine runs. Available sizes run from 37 to 88, and this particular jet provides fuel flow matched to what the engine needs, so it plays an important role in the scooter's overall performance.\u003c\/p\u003e\u003ch3\u003eHow Main Jets Work\u003c\/h3\u003e\u003cp\u003eA main jet sets how much fuel gets mixed with incoming air as it enters the engine. On Small Frame Vespas, it operates alongside an idle jet to keep the engine running smoothly. When more power is called for, the main jet passes a larger fuel flow, which helps with throttle response during acceleration.\u003c\/p\u003e\u003ch3\u003eSigns It May Need Changing\u003c\/h3\u003e\u003cp\u003eWeak acceleration, uneven engine behavior, or trouble starting can all point to the main jet being worth a look. Finding the right jet usually takes some testing, since each engine setup differs. Jetting guides are a useful reference when adjusting your scooter's carburetion.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e #64\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePosition:\u003c\/strong\u003e Main Jet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Small Frame Vespas with 16mm and 19mm SHA\/SHB carburetors, and PHBG carbs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eCompatible with:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSmall Frame Vespa with 16mm carburetor (SHA\/SHB)\u003c\/li\u003e\n\u003cli\u003eSmall Frame Vespa with 19mm carburetor (SHA\/SHB)\u003c\/li\u003e\n\u003cli\u003ePHBG carburetor\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eHow to choose:\u003c\/strong\u003e Select #64 only when you need that main jet size for your carburetor.
