How to install the accelerator line of Longxin 125 motorcycle carburetor?

When installing the carburetor, first put the throttle line through the upper cover of the carburetor, then put the spring around the throttle line, then extend the throttle line through the hole (the pipe you mentioned) of the throttle valve, pull it out from the next slot to the end, and loosen the head of the throttle line from the Mekong River slot at the bottom of the throttle valve. When installing the throttle valve into the carburetor, pay attention to point the throttle valve toward the idle screw with a slight inclination. Extend a long slot to the bottom, toward the convex side of the carburetor, and then screw on the cover. At this time, you can see that the throttle valve has dropped from the throat of the carburetor to the bottom, indicating that it is installed correctly. Please refer to the figure below.
