About the Flywheel Key

The flywheel key might have sheared in half. The flywheel key is a small metal piece which fits into the crankshaft and engages with the flywheel. If the snowblower engine stops suddenly due to hitting a hard object, the flywheel key breaks in half to prevent damage to the engine. To determine if the flywheel key is broken, remove the flywheel from the engine and inspect the flywheel key. If the flywheel key is broken, replace it.
