You move the dist body one way and the wires another. If you are running out of room to move the dist often this works. As Kent says you can move the gear. If the engine is not "sludged" or varnished up, just stick a screwdriver in the gear slot. I forget which way, just try it--one way will "walk" the gear up out of the helix and you can change the position.
You can mark the dist body with their silly gauge then sub the cap and orient that with respect to the mark, and make a mark relative to each adjacent tower.
Rotor phasing does not set the timing. All this is doing is determining where the rotor to tower position is located when the spark fires, and because it's electronic, and not mechanical advance, the two are not 'locked'
