7. MAGNETO
7-1 MAGNETO
The Robin Engine uses a T.I.C. type breakerless magneto ignition system.
(1) T.I.C. (TRANSISTOR IGNITER CIRCUIT) has the ignition coil outside the flywheel, which is the standard
specification. A charge coil system is available as an option.
(The flywheel is a specialized piece of equipment.)
As for the lighting coil, the ignition coil is outside the flywheel and a lighting coil is inside.
7-2 INSPECTING THE MAGNETO
If the engine does not start, has difficulty starting, or does not run smoothly, check the magneto for defects
according to the following procedure:
(1) Carefully check the high-tension cable for any damage or short circuiting.
(2) Check the sparking.
Take the spark plug out of the cylinder head, connect the spark plug with the plug cap and ground it
on the cylinder head or any other metallic part of the engine.
(The gap between the electrodes of the spark plug should be between 0.6 mm and 0.7 mm).
Rotate the engine by pulling the recoil starter and check the spark plug gap for sparking. If the spark
plug is sparking, check the intensity of the spark.
(Before checking the spark plug, disconnect the primary wire from the connector.)
Next, disconnect the spark plug from the plug cap and check the end of the high-tension cable for
sparking.
