Small engines power the heart of many small farms, from lawn tractors to tillers. Keeping them in good condition requires consistent care and a few smart habits throughout the year.
Start by maintaining a clean air filter. A clogged or dirty filter limits airflow and affects engine performance. Foam filters can be washed, but paper filters should be replaced regularly to ensure proper fuel-air balance.
Fuel quality is another critical factor. Gasoline that sits for more than four months becomes less combustible. Always use fresh fuel and add a stabilizer only to new gas, never to old fuel.
Ethanol-free gasoline is best for small engines because ethanol absorbs moisture, causes corrosion, and can lead to ignition problems.
Checking the spark plug should be part of your routine. Investing in a spark plug checker helps identify if the plug is functioning correctly. If there’s no spark, it helps find the cause of failure. Cleaning the plug ensures reliable starting every time.
During seasonal storage, drain the carburetor to remove leftover fuel and prevent varnish buildup. If you prefer not to drain it, run the engine monthly for about ten minutes to keep internal parts lubricated and coated with fresh oil.
Finally, change the engine oil every season to maintain good compression and prevent sludge buildup.
With regular care, your small engines will deliver dependable performance and years of reliable service on the farm.
