The most common reasons your snowblower may start and then die are: Bad fuel. A dirty carburetor that is unable to regulate the mixture of air and gas provided to the engine. Too much oil is in the crankcase.
Why does my snowblower dies under load?
The most common reason for a snowblower to stall is the carburetor is clogged and needs to be cleaned. The fuel cap vent can clog, causing air to not enter the tank and vapor lock will occur causing fuel not to move within the carburetor.
Why does snow blower keep shutting off?
A clogged carburetor is most commonly caused by leaving fuel in the snowblower for a long period of time. If the fuel cap vent is clogged, air won’t be able to enter the tank and a vacuum or “vapor lock” will occur. This stops the flow of fuel to the carburetor causing the engine to stall.
Why does my snow blower run for a few seconds and shut off?
If your engine only runs for a few seconds and then shuts off, you could have a gummed-up carburetor. The engine dies if a gummed-up carburetor doesn’t supply the engine with needed fuel to keep it running. Rebuild or replace the carburetor if the engine dies soon after start-up.
What causes a snowblower to sputter?
A clogged fuel filter will also prevent the engine from getting fuel, causing the engine to sputter or run rough. Check the fuel filter and replace it if clogged. A dirty spark plug won’t ignite the fuel consistently, causing the engine to miss and sputter. Check the spark plug and replace it if necessary.
