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.)

Vacuum Advance (Hemis Only):

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 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.

WARNING:

 Before installing the MSD Distributor, disconnect the battery cables. When disconnect-

ing the battery cables, always remove the Negative (-) cable first and install it last.
