Calibration Resistor / 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.
