8-3 MAGNETO TROUBLESHOOTING
When the engine does not start or starts with difficulty, or when its operation is unstable, the following
checks will clarify if they are caused by a defect of the magneto.
(1) Check ignition cable for possible damage, worn insulator or loose connection.
(2) Check the spark.
1) Remove the spark plug from the cylinder head and connect the spark plug to the plug cap, then
ground it to the cylinder head or the like (The correct gap of electrodes is 0.6 ~ 0.7mm).
2) Pull the recoil starter to rotate the flywheel to check the spark of the spark plug and spark intensity
(disconnect primary wiring at the connector before the test).
3) If no spark is found between the plug electrodes, remove both the plug and the plug cap and place
the tip of ignition (high voltage) cable a few mm away from the cylinder head to check the spark
from the cable tip when the recoil starter is pulled.
