Carburetor

If the snowblower engine stops after a few seconds, 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 allowing the engine to only run for a few seconds. 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.

Gas Cap

If the snowblower engine stops after a few seconds, the gas cap might be defective. All gas caps have a small vent to allow air back into the tank when the snowblower engine is running - otherwise as gas is drawn from the tank it would create a vacuum. The vent can be difficult to see and there are many different types of vent. If loosening the gas cap a little allows the engine to stay running, replace the gas cap. It's sometimes possible to clean the vent, but on most newer engines the vent cannot be cleaned, the cap has to be replaced.

Spark Plug

If the snowblower engine stops after a few seconds 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.

Engine Oil

If the snowblower engine stops after a few seconds check to see if the engine oil was overfilled in the crankcase. If so, it may have leaked out through the breather and found its way into the carburetor. This is not common. If this has happened remove the carburetor and thoroughly clean out the engine oil. Then, reduce the amount of oil in the crankcase to the manufacturers recommendations.
