Thanks, Rob. I did not know all that. You learn something new every day. I still run the stock points. It is a first kick starter. I have upgraded the electrics to 12V with a Podtronics rectifier. I am running a larger ES2 carb. Prior to 1960 the Model 50 and the ES2 were in the Wideline Featherbeds. When Norton switched to the Slimline frame in 1960 for the twins, they continued to use the leftover Wideline frames for the singles until they ran out. Therefore, some of the 1960 singles are wideline, and some are slimline. I do not know the proportions of each.
I was joking about the TMI. I am an engineer. There is no such thing. I am astounded by the sheer volume and quality of the photos you took documenting the procedure. You did convince me that it is way beyond my capabilities and that I need a trained professional to do something like that for me. As they say on the telly, "Kids, don't try this at home!"
