Note: If the gear is ever replaced, MSD Gear (PN 8531) is required for replacement due to the .500"
diameter shaft.
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 and cap the
vacuum canister and plug the vacuum line.)
Vacuum Advance: The vacuum advance will advance the timing up to 10° during partial throttle driving (with
15 lbs. of vacuum). The vacuum line should be routed to a ported vacuum outlet above the throttle plates.
Note: MSD Distributors are supplied with the heavy (slow) advance springs and the 21° stop bushing
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.
