To adjust the timing on a 1992 Chevy 305, first ensure the engine is at operating temperature. Locate the timing mark on the harmonic balancer and the timing tab on the engine block. Use a timing light to check the current timing by connecting the light to the number one spark plug wire and pointing it at the timing mark. To adjust, loosen the distributor hold-down bolt and rotate the distributor slightly until you reach the desired timing, then retighten the bolt.
