About Carburetor Throttle Slides
The slide not only is used for fine tuning low throttle positions, but also houses the jet needle, lifting it out of the needle jet when the throttle is opened. The lower the number of the cutaway indicates a smaller cutaway and will give a richer fuel charge at off-idle throttle position, up to approximately 1/4 throttle, when the needle position within the needle jet has a greater influence on the fuel mixture as engine speed increases.
The top cap must be removed from the carburetor’s mixing chamber and the throttle slide assembly withdrawn. The slide return spring must be compressed to allow the needle and throttle cable to be removed. Once the slide has been refitted, the carburetor will require adjustment to optimize performance.Â
