I am currently in the process of a complete restoration / rebuild of a Lucas
The unit I am working on is from my 1955 Royal Enfield 350 G2 Bullet, although the specific parts I am interested in are the same for many British motorcycle brands from the 1950's.
I have a problem with the fixed points carrier, as shown in the attached photographs. The threads that the fixed points contact stud screw into are stripped, so I am faced with the task of either making a repair with a helicoil (if I can find the necessary gear), or some other way.
Am I correct in thinking that the thread is 5BA? I have measured the diameter with a micrometer and put a thread gauge on it and it seems to be correct for 5BA but I would like someone who knows more about these magnetos to confirm this if possible please.
My preference would be a new carrier but so far I am struggling to find one. There are some on eBay from India, although I would prefer not to go down that route due to import duties and doubts about the quality.
Does anyone know where I could get a new carrier in the UK?
