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. Figure 12 Checking Installation of the Lockout Plate. Figure 11 Removing the Vacuum Canister. RELUCTOR PADDLES CANISTER SCREWS MAG PICKUP PLATE SNAP RING VACUUM ADVANCE Your distributor is equipped with an optional vacuum advance canister. Vacuum advance is generally used to improve cruising economy and driveability, depending on the application. The chart in Figure 10 shows the relationship between engine vacuum and the amount of ignition timing advance. To connect the vacuum advance, connect a vacuum hose from the canister to a ported vacuum source on the carburetor or throttle body. Ported vaccum sources are located above the throttle plates so there will not be an excessive amount of timing advance at idle and lower engine speeds. 0 2 4 6 8 10 12 14 12345678 910111213141516 Degrees of Advance OE Non Adjustable Vac.
