How to adjust the throttle line after installing carburetor on motorcycle

There is a groove on the outer part of the throttle valve, and there is a protruding nail on the carburetor, which will not fall down in turn. The circlip has dropped, so you must match it, or the main oil needle will drop easily. The clamp spring can also adjust the height of the main oil needle, which can save oil. I forgot to install the return spring, so the throttle won't return. After installation, it can return.

Next to the carburetor of the scooter, there is a semi-circular or disc-shaped thing for installing the throttle line. Just clip the end of the throttle tube into the hole on the disc and clip the throttle tube into the groove.

There are two throttle lines on the carburetor of motorcycle, both of which lead to the throttle handle on the right side of handlebar. The top is the throttle pipe, which is responsible for controlling the throttle and the oil needle, that is, controlling the throttle. Next to it is an acceleration pump pipeline, which allows the carburetor to spray an oil to the throat when the throttle turns sharply to improve the acceleration when the throttle turns sharply. This accelerator pump only works when the throttle is sharp, but it doesn't work when driving normally or the throttle is slow. When parking a car equipped with this carburetor, be careful not to twist the throttle, otherwise it will inject gasoline into the cylinder, causing flooding and wasting gasoline.
