So I tried out my total timings again by going up in RPMs until the it stopped advancing (before in another thread I just stopped my RPMs at 2500).

12° Initial idle timing @650 RPMs (worked my light button to 12° to read 0 on the timing mark). This hasn't changed since it was set months ago.
30° ~3500 Max Mechanical (worked the light offset button to 30° to read 0 on the timing mark while holding the RPMs)
45° ~3500 Max Vacuum (worked the light offset button to 45° to read 0 on the timing mark while holding the RPMs)

So I assume that means if I now adjust my distributor to 36° @3500, my initial idle timing will move up from 12°. I assume that won't be so good? I was watching a video on YouTube and this is because the crankshaft has X degrees of timing in it? Or it is a rubbish distributor?
