MAINTENANCE

SPARK PLUG

NOTICE

NEVER use a spark plug of incorrect heat range.

1.Remove and clean spark plug (Figure 32) with a wire brush if it is to be reused. Discard spark plug if the insulator is cracked or chipped.

2.Using a feeler gauge adjust spark plug gap to 0.028 ~0.031 inch (0.7~0.8 mm).

3.Thread spark plug into cylinder hole by hand to prevent

cross-threading, then tighten securely.

V-BELT

Visually examine the V-belt (Figure 33) and determine if it is full of tiny cracks, frayed, has pieces of rubber missing, is peeling or otherwise damaged.

Also, examine the belt and determine if it is oil soaked or "glazed " (hard shiny appearance on the sides of the belt). Either of these two conditions can cause the belt to run hot, which can weaken it and increase the danger of it breaking.

If the V-belt exhibits any of the above wear conditions replace the V-belt immediately.

SPARK ARRESTER CLEANING

Clean the spark arrester every year or 100 hours.

1.Remove the 4 mm screw (3) from the exhaust deflector, then remove the deflector. See (Figure 34).

2.Remove the 5 mm screw (4) from the muffler protector, then remove the muffler protector.

3.Remove the 4 mm screw from the spark arrestor, then remove the spark arrester.
