Spark Plug

If the snowblower won't start the spark plug might be defective. All small 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 a spark plug is to use a spark plug tester. The spark plug should have a strong, visible spark between the electrodes when the engine is cranking. If it doesn't, replace it.

Carburetor

If the snowblower won't start, the carburetor might be clogged or have bad fuel in the float bowl. If old fuel was left in the snowblower for a long time some of the volatile ingredients may have evaporated, leaving a thicker, stickier product that is more like varnish or shellac. This sticky fuel can clog up the small jets and ports in the carburetor and it can be difficult to burn making it hard to start the engine. The only solution is to drain the old fuel from the float bowl and thoroughly clean the carburetor with carburetor cleaner. If that isn't effective, replace the entire carburetor.

Carburetor Kit

If the snowblower won't start, the carburetor might be clogged or have bad fuel in the float bowl. If old fuel was left in the snowblower for a long time some of the volatile ingredients may have evaporated, leaving a thicker, stickier product that is more like varnish or shellac. This sticky fuel can clog up the small jets and ports in the carburetor assembly and it can be difficult to burn making the snowblower engine run roughly. The only solution is to drain the old fuel from the float bowl and thoroughly clean the carburetor assembly with carburetor assembly cleaner. If that isn't effective, rebuild the carburetor with this carburetor kit.

If it is, the ignition coil is working properly.

Flywheel Key

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.
