Help phasing rotor with BS3 and MSD-2345

[davepl]

Between Precision Turbo not answering period and John's yes/no answers, I'm still a little hazy on the steps to check rotor phasing.

The part I don't fully get is when you drill a big hole in your distributor cap and shine the timing light in to make sure the rotor tab aligns with the cap post.

I -thought- that if the phasing wasn't right, you should just be able to rotate the distributor housing, since that rotates the cap. But why does that not change anything? Is it because the magnetic pickup for the reluctor tabs rotates too, so you're not changing anything?

Basically, my three questions are:

1) What are you looking for when you're peering in there? Just to make sure its on the right pole? Or that its not too far out of alignment?

2) How far out of alignment is too far?



3) What to do if its too far out of alignment? Is geting a phasable rotor (with the elongated screw holes) the only option?

Thanks in advance for any help... this is really frustrating, because the BS3 manual has about 12 pages on how to install a Windows setup program and -nothing- on, oh, setting up an inductive pickup ignition.
