These are the vacuum advance/retard figures for the dizzy. Please note these are additive to the static advance timing mark (e.g. CB60/61 is about 10° ish advanced and CB23 about 5° ish without any distributor influence)

CB23 Centrifugal advance 0° @ 750 rpm, 10.5° cam @ 2800 rpm.. Notch value 10.5 to 11°

CB23 Vacuum advance 0° @ -100mmHg, 11° cam @ -320mmHg (two stage)

CB60/61 Centrifugal advance 0° @ 750 rpm, 13.5° cam @ 3000 rpm. Notch value 13.5 to 14°

CB60/61 Vacuum advance 0° between -60mmHg & +100mHg, 10° cam @ -450mmHg, -7.5° cam @ + 300mmHg (retard arm starts extending at 2 psig and is fully extended at 6 psig)

Double the vacuum/pressure and centrifugal governor degrees for crankshaft °.
