(g) Install the ignition coil assembly (See page IG-10).
2. INSPECT SPARK PLUG
NOTICE:
• Never use a wire brush for cleaning.
• Never attempt to adjust the electrode gap on a
used spark plug.
(a) Check the electrode.
(1) Using a megohmmeter, measure the insulation
resistance.
Standard insulation resistance:
10 M
or higher
HINT:
• If the result is 10 M
or less, clean the plug
and measure the resistance again.
• If a megohmmeter is not available, perform
the following simple inspection instead.
(b) Alternative inspection method:
(1) Quickly accelerate the engine to 4000 rpm 5
times.
