There was a change to the case - the "diagonal" as in the photo above, and the open bottom type as I currently have which is in chocolate teapot territory on the back of a rib when the main engine telltale jets the leg of the aux and sprays a lot of salt water at the lower spark plug.....
I agree the petrol burning bit inside didn't change much in 20 odd years.
You now see why I am interested in Sam's engine!

Cool, thanks. 5 bolts on the leg - powerhead joint? A single one ahead of the shaft, the other 4 two abreast the shaft(ish) the other two behind?
Cheeky ask if you can't get a serial number - lift it to "up" position & take a pic "inside" the clamp? that should confirm it's the same type of leg.
