TIMING FUNCTIONS
Before continuing with the installation, here are a few definitions you should be aware of:
Initial Timing: This is the base timing (also referred to as idle timing) of the engine before the centrifugal
advance begins.
Centrifugal Advance: The centrifugal (or mechanical) advance mechanism is made up of weights,
springs, advance cams, and an advance stop bushing. The amount and rate of advance that your
distributor is capable of is determined by the centrifugal timing. If you ever wish to lock out the
centrifugal advance, refer to the centrifugal advance section.
Total Timing: This is the total of the initial timing plus the centrifugal advance added together. Example:
10° Initial + 25° centrifugal = 35° Total Timing (When checking Total timing, disconnect the vacuum
canister and plug the vacuum source).
Note:MSD Distributors are supplied with the heavy (slow) advance springs installed. This is to prevent
detonation in certain applications. Review the information on pages 2-4 to determine the best
advance curve for your application.
