    Without choke it cannot be started by hand. the carburetor has to be flooded until it makes a smacking noise, then it starts immediately. I own and fly this engine since three years.

      Exactly, obviously dry at the beginning, then a typical RCist grinding away with a electric starter, eventually it suck up enough fuel to pop.

    That’s a nice engine. But just for the record, a radial engine can be machined out of a single two inch thick steel plate. It would have (almost) square pistons.
    The plate would contain the crankshaft and combustion chambers, and the cylinder head would be one piece, on the side rather than the top.

    Actually it is a lack of contact that you have to have to start an aircraft engine since contact of the magneto is never broken but shorted out to keep it from firing.
