ABSTRACT:
An idle speed control mounted on the body of a carburetor for controlling the idle speed of an internal combustion engine is disclosed. In a first condition, the throttle plate is maintained in a position to provide a "normal" idle speed and in a second condition a fixed engagement between the stop means and the throttle plate provides a fast "start-up" idle condition. In a preferred embodiment in the first condition, the throttle plate engages the stop means and the engagement is variably adjustable to vary the "normal" idle speed. The engagement of the throttle plate with stop means in the second condition is stable but may be released by movement of a throttle trigger.
