This video introduced me to a new (relatively speaking) type of engine which I never knew before. A Wikipedia search has given me the idea why it is called as "Hit and miss". It seems like they can be used as range extenders for plug-in hybrid vehicles, where the engine runs a generator and does not drive the car directly. It seems that such a setup would be simpler to cool and air cooling would be sufficient. I still don't know why this design is not reconsidered for use in the automotive industry.
Runs great ! The Shop Wisdom Of Philip Duclos, from The Home Shop Machinist, 1991, its a good book, lots of interesting engines and machining ideas with plenty o pictures and drawings. You see quite a few engines from his book on display at the various engineering shows like Cabin Fever Expo;

as sometime also can be gyroscope self balancing motorcycle
I wonder what the max efficiency is of a hit & miss design. I know they have been in use for decades on donkey engines pumping oil.
