thanks for the link on OEM-type weights, Kangaroo, that will be useful info.
I don't understand why you need info on what the curve is supposed to be when you already know what is actually is and you know what you want. The last data you posted you were very close to what you want centrifugally (20° vrs 22°) and your vac advance was stopped down to 8°.
have you "unstopped" the can to see what's available?
are you using a matched pair of springs, or have you tried a lighter spring on one of the weights with a heavier one on the other to fine-tune the curve?
