I was a crew chief on a USArmy beaver in 1958, Allan Army AF. This airplane had an inertia starter that was energized by an electric motor and could also be hand cranked (for fun). Starting was crack throttle, switches on, battery on, starter motor
energizing inertia system until the cowl vibrated, hit start switch, count the prop turns, move to rich mix, enjoy the smoke and noise.
Also crewed an Otter r-1340 which had a direct starter. The Beaver must have been an old 985.
