Abstract
Abstract A unit for remotely operating an element to different positions such as start, fast, slow and stop for a driving application such as the one herein illustrated for the engine of a lawn mower. The unit is made of plastic material being molded in two parts with a recess in the side of one part which is adapted to receive a tube forming a handle. A bolt passes through a hole in the part and through the tube to which it is securely retained when a lock nut and bolt is tightened. The unit has a slot between the two parts in which a lever is movable to advance and retract one or more control wires which operate the carburetor, brake or other element of the lawn mower.
