System Precautions

A spark may occur if distributor is moved with ignition switch in the "ON" position. DO NOT remove secondary spark plug wires while engine is running.

Silicone dielectric compound must be applied to all insulating areas of distributor, coil, and spark plug boots. Coat distributor rotor tip with dielectric compound to a thickness of 1/32". DO NOT use silicone dielectric compound on multi-point rotor.
