Adjustable throttle stop

In a throttle valve control system for an automobile including an engine, a carburetor mounted on the engine, a throttle valve in the carburetor for controlling the flow of fuel to the engine, an accelerator pedal, and a throttle linkage interconnected between the accelerator pedal and the throttle valve, the improvement therein comprising:

• the throttle linkage including a throttle linkage adjustment means constructed and arranged to expand and shorten the effective length of the throttle linkage, and
• throttle closure limiting means for selectively limiting the amount that said throttle linkage adjustment means expands the effective length of the throttle linkage,
• so that when said throttle linkage adjustment means shortens the effective length of the throttle linkage, the accelerator pedal directly controls the maximum open setting of the throttle valve for maximum acceleration of the automobile, and when said throttle linkage adjustment means expands the throttle linkage, said throttle closure limiting means limits the expansion of the effective length of the throttle linkage at a predetermined maximum limit, thus limiting the closure of the throttle valve to a selected limit for decreasing the acceleration of the automobile.
