Can I take a wild stab at this? I think your feeling is correct, reasoning
thusly: on this design, as you've drawn it, the load on the edge of the fly-
wheel tooth where the pinion first engages it would be spread better through
the base of the gear, as that edge is centered over the ring. On the old fly-
wheel, the edge of the tooth would also be on the edge of the supporting ring
below it. NOTE: As I said, just a (slightly educated) guess!

P.S. Looked out the office window this afternoon and saw an AUSTIN AMERICA
parked across the street! Is this an omen, or what??? :-) :-) :-)
