In stock (can be backordered)


Top quality Taiwanese made performance and standard replacement carburetor for the ever popular 139QMB GY6-50 49cc scooter engine found also in ATV’s.

Kymco Agility, Baotian, TaoTao, Tank, SYM, Genuine, and hundreds more, Chinese or not.

These are great for performance applications with Big bore kits, performance pipes, etc, or even for standard replacement. Will last a lifetime and perform much better than that cheap chinese junk that came stock.

If you have a scooter with a 4 stroke 49cc, it’s most likely a 139qmb, just check on the left hand side of the engine under the belt cover, but you can pretty much be guaranteed this will fit.

The 139qmb is like the chevy V8 of the small scooter world, it’s everywhere.
