Loose your woodruff key? You’re not alone. These tiny things have a huge importance. When a magneto flywheel key is missing, and the nut is not fully tight, the flywheel can slip and cause the sparks to happen at the wrong time.
Above, some of Myrons keys for sale, made in Germany. L to R: 3.0 x 5.0 (M-86), 2.5 x 3.7 (M-82), 2.0 x 3.7 (M-81), 2.0 x 2.6 (M-80). They look smaller because of the rounded edges, plus the ruler is closer to the camera. These are the “sharp edge type”, but not “knife edge” sharp. The “chamfered edge type” are way more rounded at the circle edges only. A chamfered key will always replace a sharp key, but only sometimes will a sharp key replace a chamfered key, of the same dimensions.

Welcome. These are the engine nuts that go on rotating shafts, rather than stationary nuts, like the head nuts. For head nuts see Engine Top End. Some are very specific and others are more universal.
