Ignition coil (magneto module) for the Oleo-Mac 937/941C/941CX/GS370/GS410C/GS410CX/GS44/GS440 chainsaw, as well as for EFCO equipment. It produces the spark for the spark plug, working together with the flywheel. Country of origin: China.
Signs of a fault: no spark or a weak one, the engine stalls when warm, runs unevenly. Before replacement, check the spark plug, the plug cap and the wire; when installing, maintain the gap between the coil and the flywheel.
