Hi, I have noticed that you never put the rear brake arm's return spring on the brake shoe camshaft shaft. That is why there is a lot of space between the split pin and engine case. I have been watching your Vespa and Lambretta Viton seal upgrades and they are very good. Hope you make others. Regards Richy.
It did dawn on me about the spring, I did update about it, thanks for your kind words, I was in two minds as to put the brake lever on as I am repainting the back plate. 😀 good luck.
