Just looking at the advance timing curve on the wiki - https://club8090.co.uk/wiki/Pe ... nce_curves - and wondered whether the advance checks were with or without xthe vacuum advance plugged. Any one know?

Re: Quick question about wiki timing on dg
ignition timing 5°±1° BTDC without vacuum see note at bottom of page
ignition advance checks 0°-2° @ 1500RPM w/o vacuum and basic timing (0-1 @1160)
10°-14° @ 2400RPM w/o vacuum and basic timing (13-17 @2400)
24°-28° @4200RPM w/o vacuum and basic timing (24-28 @4200)
vacuum advance range 12°-16° engine degrees
idle speed 900±50 RPM
If it has digital idle stabilization then connect the two plugs together.
There were two distributers fitted to DG's..later specs in brackets.

Re: Quick question about wiki timing on dg
Thanks Martin,
Just to check those advance timings, are they plus the bdtc? So for example, 10-14 is 15-19 degrees?

Re: Quick question about wiki timing on dg
Sorry, been drinking. I meant the 5 degrees btdc.
So for example 10-14 degrees at 2400rpm + 5 btdc, equalling 15-19 degrees total advance at 2400rpm?
Hope that makes sense.
