Thanks Grumpy I read that thread.
Found out that engine has 3 main bearings.
Came across a fault today doing the carb, see image of broken fuel bowl pivot & my repair.

Still haven't found a repair manual or exploded diagram.
Found with a bit of searching, that a lot of these engines are in south Africa.
The 3 wheeled commercial mower is interesting.
