It helps control the fuel and air mixture across the lower third of throttle travel. Among the \u003ca href=\"\/collections\/scooter-carburetors\"\u003escooter carburetors \u0026amp; jets\u003c\/a\u003e available, it keeps acceleration smooth by reducing flat spots that often come from an incorrect size. Choosing the right size matters for good performance, so it helps to know what your scooter requires.\u003c\/p\u003e\u003ch3\u003eHow the Idle Jet Works\u003c\/h3\u003e\u003cp\u003eThe idle jet sits alongside the main jet and the two work together to meter fuel. A size that doesn't suit your setup can cause performance problems, most noticeable when accelerating. The jet has two separate measurements: the first gives the diameter of the fuel inlet, and the second gives the diameter of the air inlet. Changing either size can make a real difference to how the scooter runs.\u003c\/p\u003e\u003ch3\u003eWhen to Swap Your Idle Jet\u003c\/h3\u003e\u003cp\u003eConsider replacing the idle jet if acceleration feels uneven or you notice flat spots. Those symptoms usually suggest the current jet size isn't right for your scooter. Some older models use idle jets without air holes, which need particular sizes to work correctly. Keeping an eye on how your scooter behaves will help you decide when a replacement is due.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e 42\/160\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePosition:\u003c\/strong\u003e Next to the main jet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e SI carburetors on scooters and mopeds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eHow to choose:\u003c\/strong\u003e Pick an idle jet size that suits your carburetor's setup.
