The next one that popped up was a distant relative of @Michael Pickett, starting a Fordson tractor, which looks a whole lot like a Model T engine. The reason I think it's a distant relative of Mike's is what he shows us on the opposite side of the engine. No wonder it started so easily.......
Reminds me of how I modified an early magneto onto the farm's retired 1930 Caterpillar tractor but never did get it to fire up.
BTW....... What are those rear wheels - Convex or Concave?
