Default 4Th gen Timing Procedure

The only reliable way to set engine timing is with a timing light.
Prior to beginning, clean the timing tab that is on the front of the timing cover, and the balancer (particularly where the timing grove is located). To aid in visibility, I recommend you paint this grove with silver or white paint. You can also swipe silver paint over the timing cover timing tab to enhance the markings on it.
With the engine off, disconnect the 4 pin connector going to the lower rear of the distributor.
Connect the timing light's power cables to the battery.
Clip the timing light's sensor wire to the #1 cylinder spark plug wire (driver's side, front spark plug). An easy place to connect this is up by the distributor. Just make sure you have the correct wire.
With all wires clear of the fan blade and belts, start the engine.
If the timing light is the adjustable type, ensure it is in the 0 degree advance mode.
The timing light should be strobing.. or should strobe when you hit its trigger.
Point the timing light down at the timing tab on the timing cover.
If all is working properly, the timing grove on the balancer should be present somewhere in the timing tab region when the timing light strobes on.
To adjust the timing, loosen the distributor hold down bolt just enough to be able to rotate the distributor. Rotate the distributor in small increments, then recheck timing. Rotate counter-clockwise to advance timing (timing mark BTDC increases away from 0 degrees), clockwise to retard timing (timing mark BTDC decreases toward 0 degrees). Stock timing should be 6 degrees BTDC. You can increase this to 10 to 12 degrees BTDC for better performance.
Once you have the timing where you want, tighten the distributor hold down bolt and recheck the timing. You may have to bias the adjustment one way or the other to get the tightened down timing reading where you want it.
Once you've tightened the distributor bolt down the final time, you can turn the engine off. Reconnect the 4 pin connector and remove the timing light. You're done!
