Brian, Forgive me if I've misunderstood, but as the cam turns counterclockwise, turning it counterclockwise one tooth will advance it (? Won't it??).
I understand exactly what you are saying but believe it needs to go clockwise to have the effect you are saying.
That would mean the mark on the cam gear needs to be to the left (as viewed straight on) of the mark on the crank gear.

(Hope I've got this right)

Mart.
