I took my new ATD apart (very easy), filed on the two large ears (very hard material) until I got 16 degrees of advance (32 at the crankshaft) reassembled everything, installed it on the bike, timed it to 34 degrees at full advance, 2 degrees at start. Hope all works.

I’m now looking for information on the correct routing of all the control cables and wiring for my bike, 1951 Shadow. I have the wiring diagrams, but what path do the control cables and wires take ORIGINALLY to get to from point A to B?

Best regards.
