Any up and down movement- wear- of the advance mechanism, or shudder, the cam will make life hard for the points.
If you love it, lube it.

CT 110 electronic ignition fits, MAKE SURE THE FIBRE WASHER IS IN PLACE BETWEEN THE POINTS AND BACKING PLATE.  You need to fit a much smaller needle tube to the 34mm.
