Carb is great but air intake manifold is cheap
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.

Great carb for factory replacement.
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.

Easy install but
Not big difference from original. Choke has issues still.
