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.

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.
