SPARK PLUG
(FIG. 31)
Remove spark plug and check condition. Good
operating conditions are indicated if the plug has a
light coating of grey or tan deposit. A white
blistered coating could indicate overheating. A
black (carbon) coating may indicate an over rich
fuel mixture or incorrect carburettor adjustment.
Do not sand blast, wire brush or otherwise service
a plug in poor condition. Best results are obtained
with a new plug. The plug gap should be set at
