I have ordered 3 of them now The Jets are set pre installed to run good so it's plug and play just set that idol screw Now Keep in mind on any carburetor they last 200 miles or so even my Dirtbikes was the same way Higher end or budget for the money it's wonderful especially for the price I knew buying my scooter id have to work on it and replace parts it's part of being a Rider if you're not replacing parts you're not riding enough but luckily this will last you longer than those other carburetors about 200 miles That's Alot of running for a 50cc

Tuned correctly right out of the box, bolts right on and hasn't given me a single issue. Solid work

Bought this to replace the bad carb on my kids scooter. Put it on and the it ran for 5 minutes been messing with this for over 2months off and on trying to figure out what happened. Change cdi box, checked spark even drain the fuel tank and put new fuel lines because we thought it was a bad line. Come to find out the carburetor was junk out of the box. Go figure.

Installed carb and had problems right off the bat, thought it was because of the over sized jets. Trued adjusting valves and still had issues... Eventually I took the carburetor apart and cleaned it and scooter ran like a raped ape. Once I figured that out it added 5mph to top end and great acceleration.. recamend this carb just hope you don't get a glitched one like I got. Overall I'm very pleased with my new carburetor!!!
