IGNITION SYSTEM
Conventional twin ignition is provided by two magnetos. The left
magneto fires the 1-3-5 lower and 2-4-6 upper spark plugs, while the
right magneto fires the 1-3-5 upper and 2-4-6 lower spark plugs.
Torque from the engine crankshaft is transmitted through the
camshaft gear to the magneto drive coupling. Impulse couplings or
shower of sparks magnetos are utilized to aid in starting.
