if i remember correctly - 0 is mechanical timing z is ignition.

So either set to 0 with an advance gun to 5-7 degrees.

or with a static gun, set to z

If you have a timing gun that lets you set the advance then you need to use the 0 mark, or leave it set to 0deg and use the Z mark.

If you have a fixed timing gun that doesn't allow you to set any advance, then use the Z mark.
