Description
Main Jet #74 for SHA/SHB Carbs for Scooters & Mopeds. The carburetor mixes fuel and air for your engine; jets and needles fine-tune that mixture. Shop more Scooter Carburetors & Jets.
Hard starting, bogging, surging or poor idle often point to a dirty or worn carburetor. Match the carburetor size (for example PD24J or 18mm) and intake fitment, and re-jet after adding a performance exhaust or air filter.
