Dechoke Control System




DESCRIPTION
To facilitate starting the engine when the spark plugs become fouled, such as when the engine is flooded, fuel injection is cut if the throttle valve is held wide open during cranking. This allows the spark plugs to dry and purges excess fuel from the cylinders.
