It is an object of my invention to provide an In the drawing automatic control for an air throttle or choke Fig. 1 is an elevation of the device with the valve. To this end I provide means for operating cover of the cylinder removed, the throttle which means is controlled by the lu- Fig. 2 is a plan view, and bricating oil of the engine.
