Hello again!

That's right: governor above the flywheel. Reed valve through crankcase.

Yes, in fact, my interest in the Kirby Hi-Torque is because it
was possibly our first governed 2 stroke to be used on an Australian lawnmower.
No one knew about the mower - No one knew about the engine.
It was original research that brought it to the light of day.

Now, I haven't heard anything from members.
I have found a close match to the outboard leg though:

To answer your specific questions: I have no evidence Kirby were involved in
outboard production. Also note that Victa were not involved in outboard manufacture
at this time. Villiers never were. However, Victa and Villiers engines were used by
manufacturers to make outboards in the late 1950s and 1960s.

That's all I have at the moment.
