Bring sharper throttle response to your big-bore scooter build with the Universal Parts PD20J 20 mm Type-2 Carburetor for compatible 139QMB / QMB139 four-stroke engines. Its accelerator pump supplies extra fuel as the throttle opens, while the electric choke supports cold starting.

This carburetor is primarily suited to 70cc+ big-bore conversions or compatible higher-displacement versions of the 139QMB engine family, with a 20 mm intake bore for increased airflow.

  • Electric Choke: Included cold-start enrichment unit with a two-pin male connector.
