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.
