If the snowblower won't start the ignition coil might be defective. All snowblower engines have an ignition coil. The coil is the device that provides spark for the spark plug(s). If the coil is bad power won't get to the spark plug(s). The coil is essentially a small, induction generator. It is mounted next to the flywheel. The flywheel has one or more strong, embedded magnets. As the flywheel spins, the magnet(s) zip past the induction coil, this action of a magnet passing past a coil induces a voltage. Depending on the design of the coil and the strength of the magnets, a stronger or weaker spark can be created and delivered to the spark plug(s). Each time the flywheel spins around a spark is generated. The best way to test the ignition coil is to use a spark plug tester to see if the spark plug is getting a spark. If it is, the ignition coil is working properly.

If the snowblower won't start the flywheel key might have sheared in half. The flywheel key is a small metal shim which fits into a slot in the crankshaft and engages with the flywheel. If the snowblower auger hits a rock or other solid object the sudden stoppage of the auger can cause the flywheel key to shear. The only way to know for sure if this is the problem is to remove the flywheel and inspect the flywheel key.
