Actually I realized after my above post that I was calculating the 11 degrees on the wrong side of the "10" mark. In other words with, the distributor cranked over all the way clockwise, I'm at about 9 degrees BTDC. All of this is with the jumper wire in place. The jumper wire is an odd little step, I've never had another vehicle use such a thing, but I used it nonetheless. As soon as you ground that wire, the engine rpms change, so you know it's working.
