IGNITION WIRING SYSTEM & TIMING
The ignition cables should be kept clean and properly connected. Terminals should be fully seated and the nipple assemblies should not be removed from the distributor or coil towers unless nipples are damaged or cable testing indicates high resistance or broken insulation. Cracked, damaged, or faulty cables should be replaced.

Basic ignition timing has been set properly at the factory and should not normally require adjustment.
