How do you adjust ignition timing on 2000 Honda civic Si?

Answer 1

Typically on most motors, and on all B series motors, adjusting the timing requires a timing light hooked to your cylinder #1 spark plug wire and the light pointed at the crank pully. Each time the spark plug fires, the timing light will flash and you will see a mark on the crankpully. To adjust the timing, you loosen the 3 bolts holding the distributor to the motor. DO NOT TAKE THEM OUT TO DO THIS, just loosen them enough so that with some force you can spin the distributor fore or aft of the car. I believe that you can adjust up to 5% of the timing either way by using this method, but i do not recommend doing this unless you are trained, or have some experience, and the right tools. You will see the timing mark change relative to the Top Dead Center mark either to the front (advance i believe) or back (retard) depending on how you move the distributor. Again, I do not recommend doing this without the proper tools, education, or experience.
