If your snowblower turns over but doesn't start, it's likely due to issues with fuel, spark, or air flow. First, check the fuel system: old or contaminated fuel can clog the carburetor. Draining the old fuel and using fresh fuel can solve this. Next, inspect the spark plug for signs of wear or damage. If it's faulty, replacing it may get your snowblower starting again. Lastly, ensure the air filter is clean to allow proper air flow. A blocked air filter can prevent the engine from starting.
