CHECK OF PLUG CAP

(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 2.0kΩ±0.5kΩ. (Fig. 31)

(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 Long-nose pliers. (Fig. 32)

(B)In case no connection or inconsistent connection, then check

the condition of Plug cap and 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 spring again according to the step of (1)

to avoid poor connection causing the poor sparks of Spark plug.

CHECK OF SPARK PLUG

(1) Remove Plug cap with Plug cap spring, then remove Spark plug with Socket wrench 16-17 (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. 33.

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, try [CHECK OF PLUG CAP] to detect the continuity. If required, replace Plug and recheck the sparks through the above process.
