Carburetor and Needle Screw for Rotax Max Kart Engines. This screw holds the needle jet in place, centers the carburetor return spring, and also houses the throttle cable in relation to the main throttle slide.

Made of brass and a very specialty part, this needle screw requires some patience and ingenuity to remove from the throttle slide. Once removed, the needle height can be adjusted by moving part #4 on the needle (part #3 in diagram).
