4. Ignition spark gap
The following procedure applies to all of the
spark plugs.
S Disconnect the ignition coil from the spark
plug.
S Connect the dynamic spark tester and
ignition coil as shown.
S Turn the main switch to “ON”.
S Measure the ignition spark gap .
S Crank the engine by pushing the starter
switch and gradually increase the spark gap
until a misfire occurs.
Minimum ignition spark gap
6 mm (0.24 in)
S Is there a spark and is the spark gap within
specification?
The ignition system
is OK.
