I managed to make a little film (and managed to crush my finger between flywheel and crankcase!) but you can see the clicking here.
I had previously checked the backlash with thin strips of shim metal and I seem to remember it was about 5 thou. The block isn't really tightened down yet so I just set the tappet clearances to 6 thou and did them up finger tight. I will reset everything once it it all done up properly of course.
I am sure A7 engines are assembled that make more noise than this but I want to make sure nothing it wrong or broken or likely to cause issues later on. I did try spinning it with a drill slowly from the flywheel to make sure it wasn't how I was turning it and it makes quite a racket!
