VACUUM ADVANCE LOCKOUT

If you do not want to use the vacuum advance canister

of the PN 8361/83613, 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.
