How to change the throttle line of motorcycle and how to install the carburetor plunger

To replace the motorcycle throttle line, it is necessary to remove the carburetor upper cover, pull out the throttle return spring and throttle, pass the throttle line through the groove and spring on the throttle, fix the welding spot at the head of the throttle line in the groove at the bottom of the throttle, install the throttle into the carburetor at an angle (pay attention to the positioning pin, otherwise the throttle will not fall to the bottom), and then install the carburetor upper cover. The long slot of plunger plays a positioning role and should not be used for idle knob. If the short idle button is installed backwards, it will be difficult to install even if it can be installed in the car. Even if you hit a car, the speed will be high and the mixture will be too thick. Remove it and install it, with the crescent notch facing the filter element.
