ABSTRACT:
An ignition timing control apparatus for an internal combustion engine such as an outboard motor is disclosed. The ignition timing control apparatus has a throttle switch, interlocked with a throttle valve, including a first contact closed when the throttle valve is fully opened and a second contact closed when the throttle valve is fully closed. In the former case, the ignition timing of the engine is retained in an advanced angle, thereby enhancing the acceleration while in the latter case, the ignition timing is retained in a retarded angle, thereby enhancing the deceleration. When the first and second contacts are both opened, the ignition timing is advanced corresponding to the engine speed.
