There are some points here that are still mysterious to me.
First, I thought Scott Bonnar began the 45 series with Lauson or Kirby Lauson engines, and they ran for longer on the 14 inch than on the wider versions. We had a thread about that a couple of years ago. Yet here we have an early SB45 14" mower with a Briggs & Stratton.
Second, from another thread we had a few days ago I'm under the impression that the Briggs 60102 and 60202 were both 2 HP, and the 61202 may have been 2.25 HP except we haven't been able to verify that yet. The 60102 seems to have come first of the Briggs engines on the 14" mower, then the 60202. The 61202 was probably later still.
It would be nice to try to clear up the sequence of which engine was fitted to 14" SB45s, at about what date.
