6. MAGNETO

6-1 FLYWHEEL MAGNETO
The ignition system of the EH025 is the T.I.C. (Transistor, Igniter, Circuit) point less ignition system.
6-2 IGNITION OF MAGNETO
When the engine does not start, has difficulty in starting or does not run correctly, carry out the following
checks for magneto failure.
(1) Check carefully the high voltage wiring for damage and short-circuit.
(2) Check the spark.
1) Remove the spark plug from the cylinder and connect the spark plug with the plug cap and ground
it to the cylinder. (The electrode gap of the spark plug should be 0.7 to 0.8 mm.)
2) Rotate the flywheel by pulling the recoil starter and check the spark and examine the intensity of
the spark.
3) If the plug does not spark, remove the spark plug and the plug cap, place the high voltage wire end
a few millimeters away from the cylinder, pull the recoil starter and check whether the high voltage
wire end sparks.
