Need help with rotor phasing

Remember spark will take the path of least resistance, wet spark plug = least resistance.
With the cap off line up the reluctor and pick up and look at the crank degree, this will be the starting point of the timing, once the engine is running you can't check it because the advance weights are swinging out advancing the timing which should be around 18* at or just above Idle.

18* is just a good starting point and not carved in stone
