Spark Plug
USE ONLY RESISTOR--TYPE SPARK PLUGS! SEVERE ENGINE PROBLEMS MAY OCCUR IF NON--RE-
SISTOR--TYPE SPARK PLUGS ARE INSTALLED.
1. Inspect electrodes for wear, carbon buildup, or fouling
(wet oily residue). Replace plugs if edges of
electrodes are rounded or eroded.
2. Clean with electrical contact cleaner or a glass bead
spark plug cleaner only. A wire brush or coated
abrasive should not be used.
3. Measure gap with a wire gauge and refer to
specifications. Adjust if necessary by bending the side
electrode carefully.
4. Coat spark plug threads with a small amount of
anti-seize compound.
5. Install spark plug and torque to 18ft.lbs.
6. Make sure spark plug caps are screwed completely
onto end of plug wire.
7. Apply a small amount of Nyogelt grease to inside of
plug caps and install.
8. Push cap onto plug until cap “snaps” into place.
Tor que ignition coil fasteners to specification.
