You-All 24mm CVK Carburetor for 125cc-150cc GY6 Engines

You-All 24mm Carburetor for 125cc-150cc GY6 Engines

This 24mm carburetor from You-All is built for GY6 engines in the 125cc to 150cc range and works as a substitute for a number of scooters, all-terrain vehicles, and go-karts. Its build quality matches original equipment, and it is meant to fix problems like hard starting and sluggish throttle response that often come from a worn or failing stock carburetor. If you are looking to bring back lost engine power, it is worth a look among the GY6 scooter parts available. An automatic electric choke is already fitted, so installation is simple and the unit is ready to run once mounted.

Direct Replacement for GY6 Engines

This carburetor is a drop-in option for engines coded 157QMJ and 152QMI and does not call for any alterations. It is manufactured to factory dimensions, so it should seat and operate correctly. The electric auto-choke comes preinstalled, which helps with cold starts and means the part can be fitted without extra work.

Engine Compatibility

The You-All carburetor works with a broad selection of GY6-based vehicles, including models sold under TaoTao, Wolf, Icebear, and ZNEN. Confirm that your engine code matches one of the supported versions before ordering. This part is not suitable for 161QMK or 170cc engines.
