Tuning with jets, Power valves and an O2 guage

I just ordered the Mallory kit PN 29014. It has different advance springs to tailor the curve in several ways. Some guys have mentioned to try a two-stage curve. The first moment of advance is a bit fast but then at a point the advance rate slows. This is actually designed for the very thing that I am fighting.
IF....this makes the difference, you can be sure that I will admit my stubborness and apologize.
