IGNITION SYSTEM

DESCRIPTION
In the full-transistorized ignition system, the electrical energy on the pick-up coil generated by the
magneto rotor tip flows to the transistor/ignition timing control circuit. This energy is released in a single
surge at the specified ignition timing point, and current flows through the primary side of the ignition coil. A
high voltage current is induced in secondary windings of the ignition coil resulting in strong spark between
the spark plug gap.
