2. Checking sparks of the spark plug
( 1) Remove the Spark Plug [12]<12> from the Cylinder Set PN
[19]<19>. Use a wire brush to thoroughly clean off carbon
deposits on the Spark Plug [12]<12> electrodes. If the gap
between the electrodes is improper, readjust it (see the
illustration) and if the electrodes are wet with fuel, use a
clean, soft cloth to thoroughly wipe the fuel off. Remove fuel
left in the Cylinder Set PN [19]<19> by following the
procedure below.
(a) Set the Stop Switch [106]<106> to the ON position.
(b) Hold the Spark Plug [12]<12> away from the Cylinder Set
PN [19]<19>.
(c) Position the Cylinder Set PN [19]<19> so that its spark
plug mounting hole faces down.
(d) Pull the starter grip a few times.
(2) Insert the Spark Plug [12]<12> into the plug cap and place
the electrodes of the Spark Plug [12]<12> in contact with
the metallic portion of the engine (but avoid the area near
the Spark Plug [12]<12> mounting hole on the Cylinder Set
PN [19]<19>). Under these conditions, pull the starter grip.
(3) When the Spark Plug [12]<12> functions properly, the Spark
Plug [12]<12> electrodes make a snapping sound to
generate sparks.
