The protruding screw on the carburetor is used to adjust the idle speed. After you set the car on fire, let it stand still, and then screw the screw, and the idling meter will change. Turn it clockwise, the idle speed will be high and the engine sound will be loud. Turn it counterclockwise to the left, the idle speed will be low and the engine sound will be reduced. 125 motorcycle, 1500 rpm is the most suitable, that is, start the motorcycle idling. If the idle speed is high, it will do great harm to the car; If it is low, it is easy to stall or fail to start.
