NOTICE: Do not use petroleum solvents, pressur-

compressed air on the filter.
5. Check for loose, clogged or damaged air intake
hoses.
6. If necessary, vacuum or wipe out any loose dirt or
debris from the air cleaner housing and cover.

1.
With the engine cool, remove and inspect the spark
plugs. See SCHEDULED MAINTENANCE CHART
on page 166.
Fouled spark plugs are indicated by a wet, black appear-
ance. This could be caused by a dirty air filter element or
other restrictions in the air intake system. Incorrectly
adjusted valves, spark plug wires which are in poor condi-
tion or poor quality fuel could also contribute to the prob-
lem.
2.
Clean and gap the spark plugs to 0.028 - 0.032"
(0.69 - 0.84mm) (Ref. Fig. 10). If a plug has been
burned beyond 0.032" (0.84 mm) or if the porcelain
insulator is cracked, both plugs should be replaced.
NOTE: See REPLACEMENT OF MAINTENANCE
ITEMS on page 168.
3. Lightly coat the threads with anti-seize compound.
4. Tighten spark plugs to 16.2 - 23.6 ft. lbs. (22 - 32
Nm) torque.

NOTICE: Do not sand blast spark plugs. Clean with
a scraper or a wire brush by hand, and wash in a
commercial solvent.
Use care not to over tighten the plug. Over tighten-
ing can damage the aluminum cylinder head
threads.
