Hi Greg,
I do not generally have too much to do with ride-on mowers (hopefully one day) but I have been quietly following your thread here, and I would just like to add my congratulations on a beautiful restoration, of a great, and rare, machine.
Is there any chance you also took some 'exploded' images of the engine, while you were restoring it? I would love to see some more detail of this particular engine, if possible.
Again, Congratulations mate, it is good to see a hard to find piece of history, like this one, restored rather than lost.
