GY6 50cc Carburetor for 49cc 50cc Scooter Moped Carburetor, 139QMB High Performance 4-Stroke Carb with Intake Manifold, Fits PD18J Engine

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.

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.

No g Y6 carburetor is hard to beat I still got drinking on that old old Chinese scooter and run like a scouted dog what a scooter 75% and sold it for $400

Funciona muy bien

I bought this product. It works. That's the main thing. Had to do minor modifications. The muffler filter was different. Some fuel ports were missing. Used old w/gaskets. Easy install.

I was skeptical at first about getting this carb. But I got it and I am VERY IMPRESSED. Not only is it above standard quality the inside has been polished. I ordered another carb from the local cycle shop by me ( pd18j ) and compared them. This one is way better quality! Only thing I had to do was adjust A/F ratio which is super easy if you can tune by ear. It came with a 78main and a 33pilot I know that the description gives two different main sizes. So I am verifying that the one I received was a 78 main the filter doesn't have a lip on the inside and doesn't block any venturies on the filter side of carb. I did also move needle position down one. All in all this company has not disappointed me at all!! **. The intake manifold where the gasket goes is a little rough pull rubber ring out and put BLUE etc gasket maker in the channel smooth it to level and set the ring in where it outrudes halfway out ** ( perfect seal ).
