I have tried the MS table generator and it generates max advance of far more than the factory distributor my engine came with. I have had the bast performance and mileage with what is in the current tune I shared.
I also can not get the engine to idle low enough with the high advance numbers down at idle range in the MS generated table.
The bentley manual states that the timing should be set for 3º ATDC with the stock distributor at 800-1000rpm ( the stock distributor had a double action vacuum advance on it with ported vacuum retard at idle and vacuum advance off idle.)
I really wish I had a distributor dyno so I could really see what the advance curve looks like.
I used these values from the bentley to come up with my table:
049 905 206B (distributor p/n)
1050-1400------advance begins
2200-------------15-20º
4000-------------22-26º
5000-------------16-30º
I also had taken a previously generated spark table from the generator, scaled it down and mashed it up with averaged numbers from above in my generation of the current table.
all that being said I don't mind a little experimentation. I mean this whole thing is a big experiment isn't it?
