A bit more info on this mower.
Yes bigted, I measured the base, it is indeed 19".
The output shaft is 1"
It has a cast iron sleeve in the bore. (checked with a magnet)
The bore is discoloured/stained but looks and feels good.
Also noticed on the cowl sticker "Diamond edge" which doesn't mean a lot to me.
All is looking OK, next I will rinse the engine out with fuel.
Lap the valves.
Cut some gaskets.
Reassemble the head.
Give the carburettor some attention.
