Review on NIMTEK GY6 50cc Scooter Carburetor - Upgraded Four-Stroke Jet for Scooters, Mopeds, and ATVs by Shawn Price

I installed the carburetor and had problems straight away, I thought it was the oversized injectors. Valves adjusted, problem persists. I ended up disassembling and cleaning the carburetor and the scooter ran like a raped monkey. Once I figured it out, it added 5 mph to the top speed and great acceleration. I highly recommend this carb, just hope you don't have a crash like mine. Overall I am very happy with my new carburetor!
