Can I suggest you join the Smallframe forum, some experts on there. I've never come across a spacer between the casing and the bearing as standard.

Me neither.

I'm pretty sure the original "small door" small frames used a spacer. These are the engines with smaller cylinder spigots and two pronged sliding dogs in the gearbox. Here is a parts book that shows the spacer you are talking about:



I'm pretty sure they did away with this spacer when the original primavera came out.

Interesting, I've never worked on one of the real early motors, nice bit of info.
