Can anybody explain the ignition timing graphs to me?
For a 931 with the vacuum plugged off at 2000 rpm it should be 20 degrees initial advance.

at 1000 rpm what should the timing be, with everything connected?
Do I still count the 20 degrees initial advance?
The centrifugal curve says 0 degrees advance at 1000 rpm
The vacuum advance says -13 and +16 retard.
Total at 1000 rpm = 17 degrees advance??

DITC graph says it should be 9 degrees?
