Seriously...
assuming that the engine has the original front hub and crank pulley plates, turn the engine clockwise until the pin on the front cover lines up with the first notch cut into the pulley. Ignore the second notch. I do not refer to the paint colors because often they are worn or rusted away anyway.
Once you've aligned the pin and the first notch encountered during clockwise rotation, pull the CAS out. Remove the lid. On the gear is a small machined dimple, and on the aluminum body is a small notch sticking out. Align them.
Now grasp the top of the CAS body with both hands, thumbs inside on the CAS rotor to hold it still.
Insert the CAS into the engine slowly, with the stud about halfway in the adjustment slot on the CAS. You'll feel the CAS teeth engage the worm gear inside the engine, and when this happens the CAS will tend to rotate slightly, this is okay. Push it all the way down and when you're done the stud on the front cover should be sitting approx 1/4" from the left edge of the adjustment slot....a little less than halfway across.
If it tends to be in some largely different position in the slot, then you may be a tooth off and you need to remove the CAS and stab it again.
Once you do this ground the initial set coupler, fire up the engine, let it warm up fully and idle settle as low as it can, and use a timing light set to zero advance with the probe on L1 wire, and fine tune the CAS rotation until the mark lines up with the first notch under the timing light. You won't be able to get it perfect and it will tend to skip around a bit, but take the position that it stays in MOST of the time and use that as your reference.
