Fixed Ignition System
This system uses a capacitive discharge (CD) coil. Ignition timing and spark remains constant regardless of engine
speed. Timing of spark is controlled by location of flywheel magnet group as referenced to engine TDC. A typical fixed
ignition system consists of:
● 1 magnet assembly which is permanently affixed to flywheel.
● 2 electronic capacitive-discharge ignition modules which mount on engine crankcase.
● 1 kill switch (or key switch) which grounds modules to stop engine.
● 2 spark plugs.
