MAINTENANCE

SPARK PLUG

NOTICE

NEVER use a spark plug of incorrect heat range.

1.Remove and clean spark plug (Figure 28) 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.

GAP

.028 - .031 IN.

(0.7- 0.8 MM.)

V-BELT

Visually examine the V-belt (Figure 29) 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.
