Timing Curve
MSD is a GM Delco type advance, right?
You might have to bend one of the spring loops a little bit.
There are two variables with every spring:
Spring rate.
Length.
The force restraining the weights from moving depends on how much the springs have stretch.
L i is the initial length of the springs when stretched over the perches.
The amount the springs stretched or extended is the variable MSD doesn't mention.
But that's the one that lets us change the starting rpm without changing the slope.
You could try to so some measurements with calipers and math first, or just dive in and bend the loop of one and see what happens.
Force = spring rate x distance stretched.
