Quick Answer
A generator may not start after winter storage due to fuel degradation, clogged fuel lines, or corrosion from moisture accumulation.
Stagnant Fuel Issues
When a generator is in storage for an extended period, the fuel inside can degrade, causing problems when it’s time to start the engine. Gasoline can become varnish-like and gummy, clogging the fuel system, while diesel fuel can break down into acids that corrode metal components. To avoid this, consider using a fuel stabilizer and draining the fuel tank after winter storage to prevent damage.
Corrosion and Moisture Accumulation
Moisture accumulation is another common issue that can prevent a generator from starting after winter storage. When a generator is exposed to humid air, moisture can seep into the engine and fuel system, causing corrosion and electrical issues. Inspect the generator’s air filter, spark plug wires, and other components for signs of rust or corrosion. Use a wire brush to clean any corroded areas and replace the spark plug wires if necessary.
Proper Maintenance and Storage
To ensure a smooth startup after winter storage, follow proper maintenance and storage procedures. Store the generator in a dry, well-ventilated area with the fuel tank drained and the air filter removed. Regularly check the owner’s manual for specific storage and maintenance recommendations, as different generators may have unique requirements. Additionally, consider using a generator cover or tarp to protect the engine from dust and debris.
