Magneto key, 1 pc. A small part that keeps the flywheel on the crankshaft of the Good Luck chainsaw from turning and thereby preserves the ignition timing. Country of origin: China.
Replace it if it is crushed or sheared: then the flywheel shifts, the spark appears at the wrong time, the engine starts poorly and loses power. The key is usually checked every time the flywheel is removed.
