    Thanks Ken, those numbers are with the spark at full advance.  

    I've been trying to source as much info as I can on the NS2 magneto and it's bits and pieces here and there!

    I want to verify that the marks on the rotor fiber gear and the mark on the metal gear behind the breaker cam match up.  I've located them both and marked them with a spot of paint, but I cannot see the area where they should meet...it's hidden.

    Do I :

    A)remove the rotor assembly.

    or

    B) remove the breaker plate assembly?


    If taking one or both off will I see where those two gears mesh?


    ...AND, how do they come off?

    The timer marks should align at 12(steel gear  and 6 o'clock Fibre gear     Exactly straight up and down., This will not affect Cam timing but if wrong can affect   spark delivery  point with regards to Advance Retard!

    Hello Harry , You may already have this but note the correction I made and George agreed the original counter clockwise of fibre gear was wrong , steel gear goes anti-clock , fibre cock-wise . Easiest is to remove the points plate to see properly .

    Thank-you both!  Looks like the two long studs that the breaker cover mounts on also hold the breaker plate, or rather they hold the copper "springs" that hold down the breaker plate assembly.
