Yep, just as mustafagander put it - the Wright Cyclone was started on the primer, the mixture being selected to Auto Rich once it had caught. You certainly needed lots of hands; the starter energise/mesh switches were high up on the right for the PM to operate with the primer over on the left to be blipped by the PF.
So; 15 seconds to energise the starter flywheel before going to mesh (that took 2 hands!) After a minimum of 3 blades (i.e. one full rotation) the roof mounted Ignition went to Both. Hopefully the engine would fire, but may need judicious use of the Primer under it fully caught - then Mixture to Auto Rich.
The Dak was probably harder to start - especially when hot - than it was to land in a crosswind!!
