VACUUM ADVANCE LOCKOUT
If you do not want to use the vacuum advance
canister, MSD has supplied a lockout mechanism.
1. Remove the two Allen head screws that hold the
advance canister (Figure 11).
2. Remove the snap ring that holds the magnetic
pickup assembly in place.
3. Gently lift up on the mag pickup plate and slide
the vacuum canister out.
4. Install the Lockout Plate in place of the canister.
Install the two retaining screws.
5. Install the supplied screw and washer through the
Lockout and tighten.
6. It is important to make sure the pickup plate
is parallel with the housing of the distributor
(Figure 12). If it is cocked or slanted, the paddles
of the reluctor may contact the pickup. Check
the clearance by rotating the distributor shaft.
If necessary, use the supplied shims under the
Lockout hold-down to correctly position the
pickup plate.
Note: If no shims were required, use one beneath the
washer of the Lock-Out Hold Down Screw.
Note: Do not forget to plug the original vacuum
advance hose.
