Magneto’s lead

Skewing the points housing is less of a bodge than riding around with two different ignition timings.

True, but the chance of upsetting the centering of the armature shaft when bodging the points housing, is not in my playbook.
Shifting the cam ring inside the cam ring housing is the proper method, and IMO, is not much harder to do than the bodge.

Do you know if Brightspark accurately timed it to fire 0 and 180 degrees?
If yes there may be a difference in points gap if the y "shimmed" one corner to correct an incorrect timing.

I payed 350 gp for rebuild my magneto and hope they did a great job!

??? how, with a moving cam ring? ie 1962 88SS with cable advance.
To me making the armature run, dead center, in the center of the bearing carrier/cam ring housing is the only way...there is NO points housing... points sit on the end of the armature and go along for the ride.

I’m not saying tilting the housing isn’t a bodge (though I’ve done it successfully), but the bearings can accommodate the misalignment.

Dave:

Perhaps a poor choice of words or semantics.
I do know the armature is centered by moving the bearing carrier/cam ring housing. I was answering another poster who referred to the cam ring housing as the points housing, and I simply went along with it. My bad. I have edited my previous post to remove the inappropriate choice of words.

If the point gaps are unequal when getting the armature dead center, then the only way to make then equal is to shift the cam ring laterally (within the cam ring housing) on the diameter of the ramps. This is explained in my tutorial "Setting Up and Timing a K2F" https://www.accessnorton.com/NortonCommando/setting-up-and-timing-a-k2f-magneto.19685/

Take that up with Dynodave, ... he's already on my arse!!
