Has anyone had a magneto that would drop one side only, when slowing down the engine to a very slow idle. Then it starts to miss on only the right side. I think I have finally figured it out. Thoughs, theories.......

Since I had measured the gauss of the magneto armature gap, as a lark, I was curious to see if there was any magnetic strength on the armature alone in free air. To my amazement, I found a residual magnetism ON the armature. This was about 10% of the basic magnetism of the body. So the armature will ADD 10% to the field when aligned in the aiding direction and subtract 10% while aligned in the opposing direction. Potentially making a 20% total differential.
When at idle, the side with 10% less spark fails to jump the gap. As it speeds up the bike runs fine.
