For the Ignitor II, remove the distributor cap and look inside. That will probably be easier with the aid of a mirror. Down below the rotor, note the position of the rotating reluctor and the stationary pick-up/ sensor. Loosen the distributor clamp, and rotate the distributor body as required to bring the pick-up into 'eyeball' alignment with the reluctor. That won't be perfect, but it should be close enough to allow the engine to start. Once it's running at idle, use a strobe timing light to accurately set the timing.
Remember to maintain inward pressure on the distributor whenever the clamp is loosened.
Whenever you're timing a running engine, keep your whits about you, and be very aware of all the moving belts and bits at the front of the engine. Be safe.
There's another factor that Pertronix calls 'phasing', which has to do with the position of the pick-up in the distributor. The pick-up isn't accurately keyed into the distributor's plate, it can move around a bit before the mounting screw is tightened. It's final "Position" is where you put it.
The spark is supposed to fire 'just' as the the LEADING edge of the rotor aligns with the spark plug terminal on the distributor cap. If the pick-up is perfectly positioned, that will happen. But, when you eyeball align the rotor and pick-up, if the rotor's leading edge is not correctly aligned with the terminal, then it is the pick-up that is out of position... it's 'phasing' is wrong.
Loosen the pick-up and move it as required in order to allow the rotor to align with the terminal at the same time that the pick-up aligns with the rotating reluctor, then tighten the screw.
Said another way, turn the distributor to align the leading edge of the rotor with the spark plug terminal on the cap. Then loosen the pick-up, and move it as required to bring it into eyeball alignment with the reluctor.
Start the engine, and accurately set the timing with a strobe timing light.
