Q: How do I set the ignition timing to factory specs?
A: Follow the procedures below.
Timing Adjustment
Follow these steps to set timing to factory specs.
1. Make sure you have the timing belt cover installed (or at least the lower part around the crankshaft pulley)
2. Put timing light connector on #1 spark plug wire (nearest the front of the car).
3. Locate distributor hold down bolt and use a 12+" long 3/8" extension and ratchet to loosen bolt. You only need to turn it a small amount...just enough to release the tension.
4. Unplug spout connector (small gray plug located within 6" of ignition module that's bolted to the side of the distributor, the plug is located within the ignition harness).
5. Make sure the timing light wires are out of the way of the engine pulleys.
6. Start car.
7. Point timing light towards the timing marks near the crankshaft pulley on the timing cover.
8. Locate the 10* BTDC mark on the cover (factory setting) and turn the distributor slightly until the "notch" in the pulley lines up with the desired timing (10*BTDC).
9. Once the desired timing marks are lined up tighten the distributor hold down bolt.
10. Recheck timing to make sure the distributor didn't move when tightening it down.
11. Plug in Spout Connector and check timing, it should be advanced to 20 degrees or more now and move with rpms.
12. Shut off engine, remove tools, close hood, and enjoy your new found power.
Timing Adjustment/Reset Without Timing Cover
Follow these steps if you don't have a timing belt cover and have thrown the timing belt.
1. Turn over the auxiliary pulley if you can't see the timing mark that is on it. Sometimes the aux pulley is reversed so that you can't see the timing mark that is on it. The aux pulley is the same part as the cam pulley but everyone that I have seen is turned over so that you can't see the timing mark.
2. Turn the crank so that the crank bolt, the TDC mark, the aux pulley bolt and the auxiliary pulley timing mark form a straight line. The crank and aux pulley timing mark's will not be next to each other but both will be pointed in a straight line with the crank and auxiliary bolts towards the driver's fender.
3. If you can't or haven't turned over the auxiliary pulley just check to see that the rotor button is pointing to the Four O'clock position
4. Check the distributor. The rotor should be at about the 4 o'clock position, if not move it now. The crank and auxillary pulley and distributor are now aligned.
5. Now put a straightedge or piece of wire in a straight line between the cam pulley bolt and the auxillary pulley bolt.
6. Turn the cam until it's timing mark is in line with this straight line.
7. You're done. If you are stuck somewhere this method will set the timing to Zero Degrees BTDC. This is an emergency method only. It will get you home however. Once you get home, adjust timing to 10* BTDC as shown above.
