The ignition coil (magneto module) generates high voltage for the spark plug of the Good Luck chainsaw. It works together with the flywheel: the magnets induce a current, and the coil converts it into a spark.
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.
