The <strong>Woodruff key<\/strong> is the <strong>small semi-circular metal key<\/strong> that locates the <strong>flywheel<\/strong> in the correct rotational position on the <strong>crankshaft<\/strong>, ensuring the <strong>ignition timing<\/strong> is set accurately relative to <strong>piston<\/strong> position. It is designed to shear on <strong>hard impact<\/strong> \u2014 such as when the <strong>chain<\/strong> snags or the saw strikes a <strong>solid object<\/strong> \u2014 acting as a sacrificial component to protect the <strong>crankshaft<\/strong> and <strong>flywheel<\/strong> from more serious damage. A sheared <strong>Woodruff key<\/strong> causes the <strong>flywheel<\/strong> to slip out of position, resulting in incorrect <strong>ignition timing<\/strong>, difficult starting or a complete no-spark condition.
