[2] DISASSEMBLY/ ASSEMBLY
[2]-9. Ignition coil
DISASSEMBLING
(1) Remove Sprocket guard, Guide bar and Saw chain from
the machine.
(2) Remove "Recoil starter section". See [2]-7.
(3) Remove Flag terminal on one of cable end from Ignition coil.
Note: The other cable end cannot be removed from Ignition coil
because they are integrated as a Cable harness.
(4) Remove two M5x20 Hexalobular socket head bolts. (Fig. 21)
Ignition coil with Cable harness is removed from Flywheel.
(Fig. 21)
Note: Do not lose two Isolating washers between Cylinder
and Ignition coil. (Fig. 22)
ASSEMBLING
Refer to Figs. 22 and 21.
(1) Insert two Isolating washers into two seated holes of Cylinder.
(2) Pretighten Ignition coil in place by tightening two M5x20
Hexalobular socket head bolts through Isolating washers.
(3) Insert 1R366 between Ignition coil and Flywheel and adjust
the clearance of 0.25 to 0.3mm as follows:
• Once unscrewing two M5x20 Hexalobular socket head bolts,
Push Ignition coil toward Flywheel carefully and check the
clearance. If the above clearance is obtained, tighten the bolts
to fastening torque 5 ± 0.5 N·m.
(4) Connect Flag terminal of Cable harness to Ignition coil.
[2]-10. Air filter, Carburetor, Intermediate flange
DISASSEMBLING
Note: Drain Fuel tank before disassembling Carburetor.
See Fig. 23. (1) Remove Hood by inserting the tip of 1R186 from the cross slit of Plug and turning M5x20 Hexalobular
socket head screw in Hood counterclockwise.
(2) Turn Choke lever to the position of "STOP" to prevent dirt from entering into Carburetor.
(3) Remove two M4x40 Hexalobular socket head bolt on Intake manifold.
(4) Remove Air filter cover, Air filter, and Intake manifold.
(5) Remove one end of Tube 3-70 and one end of Tube 2.5-72 from Carburetor. (Fig. 24)
Note: Gasoline is left in Tube 3-70, and therefore, clean the gasoline with a cloth.
(6) Remove Carburetor from Throttle linkage.
Note: When setting Carburetor in place, hook Throttle linkage to the hole of Lever-throttle (designated by Black arrow in
Fig. 23).
