My old straight tailed 172 had dual impulse mags. Made for very easy
handpropping, which was often required because of the cheesy 20 amp
generator.

Most of the later model Lycoming powered Cessnas and Pipers that I've
seen have the impulse mag on the left only. Piper started doing this
in the Cherokee model right after they quit using shower of sparks.
Standard start procedure was : key switch on the left mag and hit the
starter button.
