Ignition Timing

CAUTION: Some tachometers may not be compatible with ignition system. Consult tachometer manufacturer before connecting tachometer to system. To avoid possible damage to ignitor and/or coil, DO NOT allow tachometer terminal to become grounded.

Warm engine to normal operating temperature. Shut engine off. Connect timing light. Connect tachometer to proper terminals of data link connector. See Fig 1.
Install Jumper Wire (SST 09843-18020) between terminals TE1 and E1 of data link connector located in engine compartment. See Fig 2. Start engine. Ensure idle speed is within specification.
Ensure base timing is within specification with engine at specified RPM. See IGNITION TIMING table.
NOTE: Timing marks are located on front cover.
Adjust ignition timing by rotating distributor. Tighten distributor hold-down bolt. Remove jumper wire from data link connector and ensure advance timing is within specification. See IGNITION TIMING table.
