Ignition Timing

  2. Disconnect the single wire in-line spout connector or remove the shorting bar from the double wire spout connector (spout connector breaks out of wire harness just before TFI module connector on distributor).
  3. Start engine and warm to normal operating temperature. Set engine idle to RPM specified on Emission Control Label. Check timing, adjust if necessary. See IGNITION TIMING SPECIFICATIONS  table. Turn off engine, remove test equipment and restore spout connection.
