After adjusting the basic ignition timing, recheck the idle rpm and secure the distributor.

Loosen the distributor hold-down bolt allowing the distributor to be turned with some resistance and adjust the basic ignition timing to the specifications on the VECI label.

If the basic timing is NOT correct, proceed to step 8. If the basic timing is correct, remove the jumper wire, reconnect the vacuum lines and disconnect all test equipment.

Check the basic timing when using a power timing light).

Adjust the engine idle rpm to the specifications on the VECI label in the engine compartment.

This can be done by allowing the engine to idle for 5 to 10 minutes when the ambient temperature is around 21вЊ (70вЏ).

Bring the engine to a normal running temperature.

If a magnetic timing unit is not available, use a conventional power timing light connected to the number one cylinder spark plug wire.

Using a magnetic timing unit, insert the pickup probe into the open receptacle at the left of the engine between the power steering and the water pumps.

Install distributor hold-down clamp screw. Make sure all high-tension wires 'snap' firmly in cap towers. Lower distributor into opening, connect pickup coil leads and install distributor cap.Rotate rotor to position of number one distributor cap terminal.Mark on crankshaft vibration damper should be in line with '0' TDC mark on timing chain case cover. Rotate crankshaft until number one piston is at top of compression stroke.If engine has been cranked while distributor is removed, it will be necessary to establish the proper relationship between distributor shaft and No.1 piston position as follows: Engage tongue of distributor shaft with slot in distributor oil pump drive gear.Clean top of cylinder block to insure a good seal between distributor base and block.

Align rotor with marks previously scribed on distributor housing. Make sure rubber 0-ring seal is in groove of distributor housing. Carefully lift distributor from engine.Remove distributor hold down clamp screw and clamp.Scribe a mark on the edge of distributor housing to indicate position of rotor as reference when reinstalling distributor.Unfasten distributor cap retaining clips and lift off distributor cap.Disconnect distributor pickup lead wire at wiring harness connectors.
