Hi Rockit
Good to see you making a heap of progress. Your ignition looks like it is a series 1 Witt the first were alloy then later blue anondised so the same as the one I am still running in the Corsa.... if you go here you can see how to set the switch positions to achieve the curves.. I am running curve 5 on the Corsa but am thinking will eventually go to another ignition which will be a lot friendlier on the starter clutch.

Curve 1 [32deg] - as set by the manufacturer
Curve 2 [26 deg] - use with very poor petrol or pre-ignition with poor petrol
Curve 3 [29 deg] - use with poor petrol or pre-ignition
Curve 4 [32 deg] - revs limited to 6500 for 'running in'
Curve 5 [34 deg] - as set by manufacturer, but with a different max advance
Curve 6 [34 deg] - for motors with lower performance at low revs (e.g. 3-in-1 exhaust)
Curve 7 [36 deg] - as set by manufacturer, but with a different max advance
Curve 8 [36 deg] - for motors with lower performance at low revs (e.g. 3-in-1 exhaust)
Curves 1-8 are set by the first 3 DIP switches. The fourth DIP switch puts the unit in test mode
If you check this post then you should get some idea of what the differences in the curves are...
am sure if you use the search function you can find a lot more info on these ignitions in particular for use with your fuels in the U.S.
