IIRC, the rotor is supposed to be just PAST the #1 terminal on the cap.

How about some details/back story?
Why are you having to do this in the first place? Was distributor removed? Engine swap?
Base timing is controlled by the computer. If distributor is indexed properly and all plug wires connected properly, check your fuel pressure with a gauge. Backfiring out of the intake is often due to a fuel/air imbalance. For a 92, you should see 31 psi at idle. Then disconnect the vacuum line leading to the fuel pressure regulator and pressure should jump to approximately 39 psi.
