    How can you adjust your car's ignition timing?

    A:

    To adjust the ignition timing on an older car with a distributor, wire up a timing light and run the engine with the light pointed at the crankshaft and the pulley that extends from it. The notch on the pulley is the top dead center, and it should flash when the timing light hits it. Three to five degrees before top dead center is the ideal position for the distributor.
