GY6 50CC carburetor is compatible with the 139QMB carburetor used in 49cc and 50cc 4-stroke scooters such as Taotao 80cc PD18J scooters, mopeds, ATV's, go-karts, quads, and Kymco vehicles

Easy to install

Products came quick very easy installation

Got it installed pretty quick took longer to get the old one out. It's took a little to get started but after the first time it starts pretty reliably and with the new air filter felt like i got a little extra power but might just be that the old carb was junk as it was stock. Pretty easy mod for a old scooter

Part fit great and definitely improved my speed and bike falling on its face when I hit the throttle.Would definitely buy from seller again 😁

Haven't used it yet but seems good

Includes all gaskets and air filter.Bolt on/plug & play

Motor would run for a minute then it would stall. Carb would not stay running. I could not return because the carburetor had gas in it. So am still waiting for my refund. I only gave it one star because I had to. Also purchased a new carburetor installed it and Scooter ran perfect.

great buy

My cheap 50cc scooter’s factory carb was bad from the start. I purchased a second carb and it was no good. Had metal filings inside it. Installed this carb and wow! No adjustment other than idle required. Doesn’t bog. Idles great and the scooter has way more power! This kit came with everything you need to replace quite a few parts. I didn’t install the pod filter only because some say it makes it hard to tune..So I stayed with the stock air box. Based on other reviews and my experience I’d recommend this product.
