Over time, gasoline can degrade and form varnish, making it difficult for the engine to start. This issue is especially prevalent in small engines like those found in lawnmowers. Solution: Drain the old fuel from the mower's tank and replace it with fresh, high-quality gasoline. Consider using a fuel stabilizer during winter storage to prevent fuel deterioration. Clogged Fuel System: During storage, debris, water, or contaminants can find their way into the fuel system, including the carburetor and fuel lines. This can restrict fuel flow, leading to starting problems. Solution: Inspect the fuel system, clean the carburetor, and replace fuel lines if necessary. Ensure that the fuel filter is clean and functioning properly. Stale Oil: Just like fuel, engine oil can degrade over time. Old oil can become thick and lose its lubricating properties, making it harder for the engine to turn over. Solution: Check the engine oil level and quality. If the oil is old or low, change it with fresh oil recommended by the mower's manufacturer. Dirty or Fouled Spark Plug: A fouled spark plug can prevent the engine from starting. Over time, carbon deposits can accumulate on the spark plug electrodes, inhibiting the spark necessary for ignition. Solution: Remove and inspect the spark plug. Clean or replace it if necessary. Check the spark plug gap, and ensure it's set to the manufacturer's specifications.

Solution: Clean the carburetor thoroughly or consider using a carburetor cleaner to remove any buildup. Choke and Throttle Settings: Ensure that the choke and throttle settings are correctly adjusted for starting.

Solution: Review your mower's manual to set the choke and throttle to the recommended positions for starting.

A weak or dead battery can prevent the mower from starting. Solution: Charge the battery or replace it if necessary. Safety Interlock Issues: Some mowers have safety interlocks that prevent the engine from starting if certain conditions are not met, such as the blade engagement lever not being in the correct position. Solution: Ensure all safety interlocks are engaged correctly according to the manufacturer's instructions.
