Muffler Cover - Hitachi CG 24EBSP Service Manual

WARNING:
• When performing the procedure outlined above, touching any metallic portions of the Spark Plug
Ass'y BMR7A [13](13){13}<13> when pulling the starter grip will give you electric shock. Therefore,
be very careful in handling Spark Plug Ass'y BMR7A [13](13){13}<13>.
• Thoroughly wipe up any fuel around the Spark Plug Ass'y BMR7A [13](13){13}<13>, and confirm
that there is no danger of fire before checking the spark.
3. Adjusting the air gap (clearance) between the magneto rotor comp. perimeter
and ignition coil ass'y
(1) Remove the Muffler Cover [2](2){2}<2>, Cylinder Cover [9](9){8}<8> and Fan Case (A) [107](107)
{107}<107>.
(2) Loosen the two Hex. Socket Hd. Bolts (W/Washers) M4 x 18 [118](118){118}<118> so as to
temporarily secure the Ignition Coil Ass'y [119](119){119}<119>.
(3) Insert a thickness gauge between the magnetic steel portion around the perimeter of the Magneto
Rotor Ass'y [124](124)/Magneto Rotor Comp. {124}<124> and Ignition Coil Ass'y [119](119){119}
<119>, and then adjust the position of the Ignition Coil Ass'y [119](119){119}<119> to achieve a
clearance of 0.2 to 0.4 mm.
(4) Tighten the two Hex. Socket Hd. Bolts (W/Washers) M4 x 18 [118](118){118}<118> and remove the
thickness gauge.
(5) After securely tightening the Hex. Socket Hd. Bolts (W/Washers) M4 x 18 [118](118){118}<118>,
confirm that the clearance is between 0.2 mm and 0.4 mm.

4. Wiring diagram
Wiring should be done as shown in the diagram below.
The Cord [122](122){122}<122> is connected to the connector on the Ignition Coil Ass'y [119](119){119}
<119>. The Earth Cord [123](123){123}<123> is fastened to the Ignition Coil Ass'y [119](119){119}<119>
with the Hex. Socket Hd. Bolts (W/Washers) M4 x 18 [118](118){118}<118>. The Cord [122](122){122}
<122> and the Earth Cord [123](123){123}<123> are connected to the terminal of Throttle Lever (B)
[151]{151} or Throttle Lever (A) Ass'y [99](99){99}<99>. Engage the needle tip of the Metal Fitting of Plug
Cap [120](120){120}<120> into the core wire of the high tension cable. Apply two-cycle oil to the cord
mounting hole of the Plug Cap [120](120){120}<120>, and then insert the high tension cable and the
Metal Fitting of Plug Cap [121](121){121}<121> into the hole. After mounting the parts, check for sparking
of the Spark Plug Ass'y BMR7A [13](13){13}<13> and continuity of the Metal Fitting of Plug Cap [121]
(121){121}<121>.
