The Throttle Valve (slide) affects the air-fuel mixture ratio between 1/8 and 1/2 throttle, and especially between 1/8 and 1/4 throttle. Throttle Valves
come in various sizes called cutaway. The larger the cutaway (size), the leaner the fuel mixture. The smaller the cutaway (size), the richer the
mixture. Throttle Valves are sold each.
