When it comes to keeping your outdoor power equipment running smoothly, a little care goes a long way. Whether you’re mowing the lawn, trimming hedges, or powering a small watercraft, maintaining your small engine is key to avoiding costly repairs and downtime. I’ve put together this small engine care guide to help you get the most out of your equipment. It’s packed with practical tips and easy-to-follow advice that anyone can use.
Let’s dive in and make sure your small engines stay in top shape all year round.
Small Engine Care Guide: Essential Maintenance Tips
Taking care of your small engine doesn’t have to be complicated. With a few simple steps, you can keep it running like new. Here’s what I recommend:
Keep the fuel fresh. Petrol breaks down over time, so use fresh fuel and possibly add a stabiliser if you’re storing the engine for more than a month. This is the Primary Reason for Small Engine Repairs.
The number one reason for small engine repairs is poor quality fuel. This can lead to various issues, including:
Clogged carburetors
Clogged fuel filters
Corrosion or breakdown of engine components
Poor combustion and reduced performance
Difficulty starting the engine
Increased emissions
Using high-quality fuel and properly maintaining fuel systems can significantly reduce the likelihood of these problems.
Check and change the oil regularly. Old or dirty oil can cause serious damage. Most small engines need an oil change every 25-50 hours of use but check your manual to be sure.
Clean or replace the air filter. A clogged air filter reduces engine efficiency and can cause overheating. If it’s paper, replace it; if it’s foam, wash and dry it before reinstalling.
Check the fuel filter and lines. Replace any cracked or brittle fuel lines and clean or replace the fuel filter to prevent blockages.
Keep the cooling fins clean. Dirt and debris can block airflow and cause overheating. Use a brush or compressed air to clean the fins regularly.
Inspect the spark plug. A worn or dirty spark plug can cause hard starts and poor performance. Clean it with a wire brush or replace it if it looks damaged.
These steps might sound basic, but they make a huge difference. I always recommend setting a maintenance schedule and sticking to it. Your engine will thank you!

How to Store Your Small Engine for Longevity
Storing your small engine properly is just as important as regular maintenance. If you’re putting your equipment away for a season or longer, follow these tips:
Drain the fuel tank. This prevents gum and varnish build-up inside the carburetor.
Run the engine until it stops. This uses up any fuel left in the carburetor and fuel lines.
Change the oil. Old oil can contain contaminants that damage the engine during storage.
Remove the spark plug and add a teaspoon of oil into the cylinder. Pull the starter cord a few times to distribute the oil, then replace the plug.
Clean the exterior. Remove dirt, grass, and debris to prevent rust and corrosion.
Store in a dry, sheltered place. Avoid damp or humid areas that can cause rust.
By following these steps, you’ll avoid common storage problems like hard starting and corrosion. It’s a small effort that pays off big time.

Who is the Largest Manufacturer of Small Engines?
If you’re curious about the biggest names in the small engine world, you’re not alone. Knowing who makes the engines can help you understand quality and find parts more easily.
The largest manufacturer of small engines globally is Briggs & Stratton. They’ve been around for over a century and are known for producing reliable, durable engines used in lawn mowers, generators, and other outdoor equipment. Their engines are popular because they balance power, efficiency, and ease of maintenance.
Other notable manufacturers include Honda, Kawasaki, Kohler and Loncin. Each has its strengths, but Briggs & Stratton remains the go-to for many homeowners and professionals alike.
Knowing this can help you when you’re shopping for parts or service. If you want expert help with your engine, companies like freshwater small engines in Cairns specialise in servicing these popular brands, ensuring your equipment stays in peak condition.

Troubleshooting Common Small Engine Problems
Even with the best care, small engines can sometimes act up. Here are some common issues and how you can fix them:
Engine won’t start: Check the fuel level, spark plug, and air filter. Make sure the choke is in the right position.
Engine runs rough or stalls: This could be a dirty carburetor or old fuel. Try cleaning the carburetor and replacing the fuel.
Overheating: Clean the cooling fins and check the oil level. Make sure the engine isn’t clogged with debris.
Excessive smoke: This usually means too much oil or a problem with the piston rings. Check the oil level and type.
Loss of power: Could be a clogged air filter, dirty spark plug, or worn-out carburetor parts.
If you’re not comfortable fixing these yourself, it’s always a good idea to get professional help. Regular maintenance reduces the chance of these problems, but when they do happen, quick action can save you time and money.
Keeping Your Small Engine Running Smoothly Year-Round
Consistency is key when it comes to small engine care. Here are some final tips to keep your equipment running smoothly no matter the season:
Schedule regular serving and tune-ups. Even if your engine seems fine, a professional tune-up can catch small issues before they become big problems.
Use the right fuel and oil. Always follow the manufacturer’s recommendations.
Keep your equipment clean. Dirt and debris can cause wear and tear.
Store properly during off-seasons. Follow the storage tips above to avoid damage.
Know when to call the experts. If you’re unsure or the engine has a serious problem, professional servicing is worth it.
By following this small engine care guide, you’ll enjoy reliable performance and longer equipment life. And if you’re in Cairns or Far North Queensland, remember that freshwater small engines is your local expert for sales, repairs, and support.
Happy maintaining!
