50CC Carburetor 4 Stroke GY6 High Performance 139QMB Carburetor for 49cc 50cc Scooter Moped PD18J Carb Engine, 50 cc Carburetor, 50cc Moped Carburetor + Intake Manifold by

Great replacement carb for a 50cc QMB motor. Mine came with a #33 pilot jet & #78 main jet. This combination works well with stock setup. Also works well with air filter & exhaust upgrades. No tuning required unless you add displacement with a big bore kit or modify head flow characteristics, such as porting or milling.

no mucking around . just perfect . thankyou

Fit my 50cc scooter perfect and gave some good performance def a lot more top end speed idek was perfect out the box don’t even have to tweak it

This is a good replacement for the stock Tao Pony 50 carb and increases performance over stock as it comes with a bigger carb jet than the stock carb. You get alot here for the price. Air filter and boot are also of good quality.

Carb works great. Installed on a dong fang (venom x18) 50cc. Installed on 2 bikes and the spark plug didn’t work for either. The air intake manifold is cheap and cracked after only being used for about 3 weeks. Wasn’t able to use the air filter due to fitment issues. Need to get an elbow to make it work. Other than that it’s been great. Super easy to install and started right up. Much better than stock.
