Ignition module
The ignition system is either a capacitive discharge or a inductive discharge magneto, depending on the application,
contained in a single module.
• The capacitive discharge has a three leg design.
• The inductive discharge magneto has a two leg design.
• The magneto is energized by the passing of a pair of magnets mounted in the flywheel.
• Ignition timing is set by the location of the flywheel in relation to the crankshaft. Proper timing is main-
tained by a steel key.
NOTE: Regardless of which type of magneto is used, the test procedures are the same.
