If your snowblower won't start after sitting, the most likely cause is stale fuel or a clogged carburetor. Fuel can stagnate and degrade over time, leading to issues when starting the engine. First, drain old fuel from the tank and replace it with fresh fuel. If that doesn’t work, the carburetor may need cleaning or adjusting. Removing, cleaning, and reinstalling the carburetor can often resolve the issue. Additionally, check the spark plug for any signs of wear or damage and replace it if necessary. Regular maintenance is key to preventing starting problems.
