Check the engine code stamped on your scooter before ordering. Engines marked with a listed code may use this part, but compare the carburetor style, two-pin connector, mounting arrangement, and plunger dimensions against your original choke. An engine code containing “QM” or “FM” alone does not confirm carburetor fitment.
