Abstract
A method and apparatus for compensating for increased engine idle speed upon breaking-in of an engine, comprising halting a throttle valve controlling admission of air-fuel mixture to the engine in an idling position of the engine by a stopper member and gradually and automatically shifting the halted idling position of the throttle valve in its closing direction to diminish the flow of air-fuel mixture to the engine to compensate for increased engine idle speed upon breaking-in of the engine. The gradual and automatic shifting of the idling position of the throttle valve is obtained by constructing either the throttle valve, or the stopper member or both with contact portions which are relatively easily worn or deformed so that as the portions undergo gradual wear or deformation, the throttle valve gradually moves in its closing direction to compensate for increase engine idle speed.
