The previous post on this topic got me wondering. Just how different would
the two engines need to be? I'm no expert, but it seems to me cam shaft(s),
magnetos, and prop are the parts that would be different from one side to the
other. I almost forgot, reverse the polarity on the starter motor. What am I
missing?

Not speaking to the other items, but electric motors seldom run as well in both
directions. It has to do with the timing, or how far ahead of the rotation that
the magnetic fields, or windings are switched.
