Small Engine Repair Tips: Keep Your Tools Running Like New Feb 08, 2026

Maintaining your lawn mower, chainsaw, or leaf blower not only extends their lifespan but also enhances performance, reducing the likelihood of frequent, costly repairs. At Locust Mowers & Small Engine Repairs, we understand how crucial it is for you to keep your small engines running efficiently. That's why we've compiled this guide full of useful tips to help you keep your tools operating like new.

The first step to ensuring that your small engine performs optimally is regular maintenance. Regular oil changes are paramount. Just like your car, small engines need clean oil to function properly. Over time, oil can become contaminated with debris and dirt, which can wreak havoc on your engine's internal parts. Check your engine’s manual for specific oil change intervals, but a good rule of thumb is to replace the oil every 20-50 hours of operation.

Spark plugs are another critical component that should not be overlooked. They are responsible for initiating the combustion process within the engine. Worn-out spark plugs can lead to hard starts and sluggish performance. We recommend checking and replacing spark plugs annually or at the beginning of every mowing season to ensure your engine starts on the first pull.

Air filters play an essential role in keeping harmful debris out of the engine. A clogged air filter starves your engine of oxygen, making it run poorly or even choke off. Depending on usage frequency and environmental conditions, air filters should be cleaned every 25 hours of operation and replaced every 100 hours. Ensure the replacement filter matches the manufacturer’s specifications to avoid any compatibility issues.

Fuel quality cannot be emphasized enough. Always use fresh fuel and avoid using gas that has been sitting for more than 30 days. Ethanol-blended fuels attract moisture, which can cause corrosion within the carburetor. If you plan to store your equipment for an extended period, run the engine until the fuel tank is empty to avoid gumming up the system. Alternatively, use a fuel stabilizer to prevent fuel deterioration.

Blades, whether they’re mower blades or chainsaw chains, need frequent attention as well. Sharp blades ensure clean cuts and reduce the engine's workload. Dull blades tear grass, which can lead to unhealthy lawns and put unnecessary strain on the engine. Sharpen or replace blades as needed and ensure they are properly balanced to avoid excessive vibrations that can damage the motor over time.

Finally, always inspect belts, cables, and other moving parts for signs of wear or damage. Regularly lubricate these components to prevent friction damage and prolong their lifespan. Pay close attention to any unusual noises or handling issues as these might be early signs of mechanical problems that need professional attention.

In conclusion, incorporating these small engine maintenance tips into your regular routine can significantly enhance the longevity and performance of your outdoor power equipment.
