Thanks Jack,
Yes, they are my images. As I pull parts off I try and model it as accurately as possible which at times is tricky as the parts are rusty, bent, repaired or worn so I have to guess what measurement they would be if they were new. Some parts like the cutterhead chute assembly are missing. The new engine has turned out way better than I had hoped, I would like to add the throttle connection which I've discovered was vertical on the original engine but is horizontal on the new one. I'm yet to model a lot of the linkages underneath which put it in and out of gear etc - something it wasn't doing properly when the real one was running before it broke. The gear box will be a challenge also. Previously in this thread Norm and I mentioned 3D printing a gearbox if it were modelled accurately enough but it would more likely be CNC machined from a billet I reckon. Anyway, glad you like the images, I will have to get cracking and finish it off.
