Abstract
The present invention is an apparatus for controlling the idle speed of an internal combustion engine. The engine has a throttle linkage with a movable control member. The idle speed control apparatus includes a bracket, a bolt, a spring and a nut. An electrical coil on the bolt magnetizes the bolt when the coil is energized by electric current. The bolt can be advanced longitudinally toward the throttle control member under the bias of the spring by rotating the nut on the bolt in one direction, and can be retracted longitudinally from the throttle control member against a bias of the spring by rotating the nut on the bolt in the opposite direction.
