The springs will only affect the advance curve. The advance stop bushing is what's going to resolve your timing problem.
If you haven't changed it since you got it, then you would have the blue bushing. I would try swapping it with the black bushing, then I'd try the silver bushing. One of them will resolve your high RPM problem. (Probably the silver)
As for the advance curve (set by springs), you have the default factory which is 2 silver (Heavy) springs, giving you the slowest advance rate.
I would try 1-heavy silver and 1 light silver. This would give you advance curve C, instead of A. I think the advance rate can be increased only up to the point where it causes the engine to backfire.
All in all, page 2 explains it best. Page 4 explains how to set up the bushing and centrifugal advance springs.
Page two also talks about the initial timing. The advance curve ADDS to the initial timing.
Let me know how it goes!!!
