Yes Berhard - this may be a sore point
They were not equal so I used the method recommended by Slick in his K2F magneto thread - dutifully ground and packed the cam ring so that gaps were equal.
The sore point is that I've been thinking that this may not have been necessary with a straight shaft. Once the shaft is straight may have to redo
Sigh.....!

It seems the guy has decided to systematically decided to delete nearly ALL my and other posts on the K2F magneto that we wrote about Sight :!: :roll:
The Lucas cam ring may not be accurate –a new one I brought in the 1970s was 4 1/2 degrees out when clocked on a milling machine dividing head so don’t be surprised if yours is much better.
