DISTRIBUTOR REMOVAL AND INSTALLATION

Align timing mark(s) to piston No. 1 at TDC on compression stroke. Mark rotor position in relation to distributor housing. Disconnect spark plug wires and wiring harness connectors from distributor. Remove distributor hold-down bolt(s). Remove distributor.

1. To install, reverse removal procedure. Ensure mark(s) or indentations on distributor shaft and housing are aligned. Check distributor rubber "O" ring seal and replace as necessary.
2. After installing distributor, ensure distributor rotor is aligned with mark made during removal or set at cylinder No. 1 spark plug position. Check and adjust timing. Tighten distributor hold-down bolt to specification.

Distributor Hold-Down Bolt Torque Spec: 10-13 ft. Lbs.

KA24DE IGNITION TIMING

1. Start engine and warm to normal operating temperature. Turn ignition off. Disconnect throttle position sensor harness connector.
2. Start engine. Increase engine speed to 2000 RPM, 2 or 3 times, then allow engine to return to idle. Engine should be operating smoothly at correct idle RPM. Check ignition timing.
3. If ignition timing is incorrect, loosen hold-down bolt and turn distributor to adjust ignition timing. Turn ignition off and connect throttle position sensor harness connector. Recheck ignition timing.

i agree this will correct the distributor rotor alignment when you place a mark on the distributor position of the rotor segment.
