[4] DISASSEMBLY/ ASSEMBLY
[4]-8. Ignition
(1) Remove Plug cap from Spark plug, then detect the continuity between Plug cap spring in Plug cap and Earth terminal
of Ignition coil.
It is the normal condition when Tester shows 2.45kΩ±10%. (
Fig. 26
)
(2) In case of no continuity or unstable continuity, check the connection between Plug cap spring and Ignition coil as follows:
(A) Spray the lubricant in Plug cap, then pull out Plug cap spring together with Ignition cable using Pliers. (
Fig. 27
)
(B) In case no connection or inconsistent connection, then check the condition of Plug cap and Plug cap spring.
Reassemble them or replace them if they are disorder.
(C) Insert the end of Plug cap spring into Ignition cable then return them back to the inside of Plug cap carefully so as
not to be disconnected.
(D) Check Plug cap and Plug cap spring again according to the step of (1) to avoid poor connection causing the poor
sparks of Spark plug.

(1) Remove Plug cap with Plug cap spring from Spark plug, then remove
Spark plug with Wrench 17-19 (standard equipment).
Note
: When the spark area is wet with Fuel, wipe it away with a cloth and dry it
by air blow.
(2) Clean carbonized materials on Insulated part for sparking with a wire brush.
(3) Do fine adjustment of Spark plug as drawn in
Fig. 28
.
Insert 0.7mm thickness gauge of 1R366 to the clearance and adjust the leg of
Spark plug carefully.
(4) Install Plug cap with Plug cap spring on Plug and connect the plug screw part
to a metal part of Engine, then pull Starter rope slowly.
The sparks can be seen when starter rope is pulled.
(5) When the sparks can not be seen, refer to “
CHECK OF PLUG CAP (SPRING)
”
in this page to detect the continuity. If required, replace Plug and recheck the sparks
through the above process.
