SPARK PLUG MAINTENANCE
The spark plug is important for proper engine operation. A
good spark plug should be intact, free of deposits, and properly
gapped. Refer to Recommended Maintenance Schedule in Fig.
20 for maintaining the spark plug. To inspect the spark plug:
1. Open the spark plug access cover (Fig. 23).
2. Pull up to remove the black plastic spark plug boot. Be careful
not to tear any insulation or wire.
3. Use a spark plug wrench to unscrew and remove the spark plug
from the engine.
4. Visually inspect the spark plug for cracks or excessive elec-
trode wear. If the electrodes are worn or burned, or porcelain is
cracked, replace with a NGK BP4H/Torch E5T spark plug (Part
No.
56202i-102 ), available at wenproducts.com.
5. If re-using the spark plug, use a wire brush to clean any dirt
from around the spark plug base then re-gap the spark plug.
6. Measure the plug gap with a wire gauge (Fig. 24). The gap
should be 0.024 to 0.031 in (0.6 to 0.8 mm). Carefully adjust the
gap if necessary.
7. Screw the spark plug back into the spark plug hole by hand.
After the spark plug is properly seated, use the spark plug wrench to tighten it.
NOTE:
The spark plug torque is 9 - 12 N.m ( 7 - 8 ft.lb). The recommended tightening of spark plug is ½ to ¾ of
a turn after spark plug gasket contacts spark plug hole. DO NOT over-tighten the spark plug.
8. Reinstall the spark plug boot over the spark plug.
9. Reinstall the spark plug access cover.
