CENTRIFUGAL ADVANCE CURVE
SELECTING THE ADVANCE SPRINGS
The rate, or how quick the advance comes in
is determined by the type of springs which are
installed on the distributor. The MSD distributors
are equipped with two Heavy Silver springs
installed. These will give you the slowest advance
curve possible (Figure 2). The parts kit contains
two additional sets of springs which can be used
to match the advance curve to your particular
application. Refer to the Spring Combination
Chart (Figure 3) for combinations that can be
achieved.
To change the springs, remove the cap and rotor
and use needlenose pliers to remove the springs.
Be sure the new springs seat in the groove on
the pin.
