MAINTENANCE
Oil and Fuel Lines
Check the oil and fuel lines and connections regularly
for leaks or damage. Repair or replace as necessary.
Replace the oil and fuel lines every two years to maintain
the lines’ performance and flexibility.
SPARK PLUG ADJUSTMENT
1. Make sure the engine is cool before servicing the
spark plugs.
2. Disconnect the spark plug caps. Check for dirt and
remove any dirt from around the spark plug area.
3. Remove the spark plugs with a 5/8-inch spark plug
wrench.
4. If the spark plugs are damaged, the sealing washer
is in poor condition or the electrode is worn, replace
the spark plugs.
5. Measure the spark plug electrode gap (Figure 35) with
a wire-type feeler gauge. If needed, adjust the gap to
0.70–0.80 mm (0.028–0.031 in.) by carefully bending
the side electrode.

6. Install the spark plug carefully, by hand, to avoid
cross-threading.
7. After the spark plug is seated, tighten with a 5/8-inch
spark plug wrench to compress the sealing washer.
8. When installing a new spark plug, tighten 1/2 turn, after
the spark plug seats, to compress the washer.
9. When reinstalling the original spark plug, tighten
1/8 to 1/4 turn after the spark plug seats to compress
the washer.
