Description

This CVK-style 50cc scooter carburetor made by Keihin is designed specifically for 50cc QMB139 4-stroke scooter, ATV, and dirt bike engines. This carburetor is equipped with an electric choke.

Best of all, you can select your superb little 139QMB carburetor in either a standard gray metal finish or a super-cool chrome-plated finish. The chrome finish may not make this carb mix gas and air any better than the standard "carb-colored" carburetor, but it sure will look distinctive mounted on your machine's 139QMB engine.

Prior to ordering, please compare the Specs for this carburetor against your original carburetor. This carburetor is commonly used on products from Baja Motorsports, Chuanl, Geely, Kymco USA, Manco, Panterra, Peace, Roketa, Strada, SunL, Tank, and Vento. Connector color may vary.

  • Questions

    Where do the gas line run from the bottom or the top
    Going off of the picture on the website, it looks like it is on the bottom for this particular carburetor.

    Yes, you should be able to install this carburetor as-is but you may need to do some adjustments depending on your local conditions & altitude.

    Was very confused when I ordered this because there were several different options, but I think I actually chose the correct one!

    stock carburetor is sealed from factory and provides limited performance. After 3000 km I wasn't able to adjust idle speed and decided replace it for this model. I have a mallosi variator whit 8 grams rollers and everything else is stock in my daughter's TaoTao Thunder 50cc. 44 mph by gps after installed this carburetor and made minimun adjustments on the idle screw. I love it....
