I'm surprised you haven't run into a crab with 11A weights and a 68 index ring (or spark ring in your terminology) I've torn apart several that way. I dig that setup as it gives the quick initial advance of a 11A but limits it to the 8 degrees of a 68.

The most recent one I had that was had the housing hogged out to move the adjuster down to allow extreme initial advance, but then had the 68 index ring.. That one stumped me and maybe you could explain that.
