VACUUM ADVANCE LOCKOUT
If you do not want to use the vacuum advance
canister of the MSD Distributor, MSD has supplied the
distributor with a lockout mechanism. The Lockout
bolts in the position of the vacuum canister and
will hold the pickup assembly firmly in place. The
installation is easiest with the distributor out of the
engine.
1. Remove the two Allen head screws that hold the
advance canister (Figure 12).
2. Remove the snap ring that holds the magnetic
pickup assembly in place. This is easy to do with
a set of snap ring pliers by straddling one of the
reluctor paddles.
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 13). 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.

Installation Option: This Cap can
also be bolted down to an MSD
Pro-Billet or Billet Distributor base
with the supplied hardware. To
accomplish this, the spring clips
must be cut off (Figure 14).
Note: When the cap is bolted down,
the location of the spark plug wires
must be changed.

7. After checking the reluctor to pickup clearance, tighten the Lockout retaining screws and install
the snap ring.
8. Install the distributor, rotor and cap. Check the timing when complete.
Note: Do not forget to plug the original vacuum advance hose.
