Okay, thanks. It's because it's a 4 cycle, so we get 4 compression 
strokes per 2 revolutions, which works out to 180 deg per.

Reading your post, I had jumped to the conclusion that you meant to 
move it by 90 and then move it later by another 90 and so on. I see 
now that you meant, and said, just one iteration.

I'd never really noticed variations in the wear around the flywheel. 
I'll have to take a better look.
