The carburetor model of my car is KEI. Excuse me, how to adjust the mixture.

Many cars use this brand of carburetor. My Universiade 125, Lifan 125-9 are all used. Good atomization effect and fuel saving. Is your mixture too thin or too thick? Generally, it is necessary to adjust the idle screw and throttle screw, or disassemble the carburetor to adjust the position of the float needle or the main oil needle. At the same time, clean the main metering hole and idle metering hole. You'd better go to a trusted garage and ask the master to adjust it for you. My hongdu 125 is much easier to drive after being trained by the master. My family has three motorcycles, which will be much more convenient to use.
