Ignition Timing Connector: Description and Operation
In-line Connector With Shorting Bar:
PURPOSE The octane adjustment switch is used to retard the
ignition timing three to four degrees.
OPERATION When the switch jumper is INSTALLED, the timing is normal. With the jumper "REMOVED", the timing is retarded. This is done to allow for optimum spark advance for effective combustion of the
air/fuel mixture.
