The warm weather has arrived, and your lawn is starting to look a bit unruly. It’s time to get your trusty lawn mower out of storage and get to work, but how do you actually start it? Whether you’re a seasoned lawn care pro or a first-time mower owner, getting your machine up and running can seem a bit daunting. This comprehensive guide will walk you through the steps of starting a gas-powered lawn mower, covering everything from preparing the mower to troubleshooting common starting issues.
Starting a lawn mower is a simple process that involves a few key steps. Firstly, you’ll need to ensure your mower has fuel and that the engine is primed properly. Then, you’ll need to choke the engine, pull the starter cord, and repeat until the engine starts. Finally, you’ll need to release the choke and let the engine warm up. This article will provide a detailed breakdown of each step, along with helpful tips for troubleshooting common issues.
Preparing Your Lawn Mower
Before you can even think about starting your lawn mower, you need to make sure it’s ready to go. This includes a few basic steps that will ensure your mower runs smoothly and safely:
1. Check the Fuel
The most common reason a lawn mower won’t start is because it’s out of fuel.
- Check the Fuel Level: Look at the fuel tank and see if it’s empty.
- Use Fresh Fuel: If the fuel is old, it may have gone bad and will need to be replaced. Old fuel can gum up the carburetor and make it difficult to start.
- Fill the Tank: If the tank is empty or needs a refill, use fresh, unleaded gasoline with a minimum of 87 octane. Avoid using fuel with ethanol, as it can damage the engine.
2. Check the Oil Level
The engine needs oil to lubricate moving parts.
- Use the Dipstick: Remove the dipstick, wipe it clean, and reinsert it all the way. Pull it back out and check the oil level. It should be somewhere between the “Full” and “Low” marks.
- Add Oil: If the level is low, add the correct type and amount of oil. Consult your owner’s manual for the appropriate type and quantity of oil.
3. Clean the Air Filter
A dirty air filter can restrict airflow to the engine, making it difficult to start.
- Remove the Air Filter: Locate the air filter cover and remove it.
- Clean or Replace: If the filter is dirty, you can try cleaning it with soap and water. Let it dry completely before reinstalling. If the filter is beyond cleaning, replace it with a new one.
Starting a Gas-Powered Lawn Mower
Once your mower is prepped and ready, you’re ready to start the engine! Here’s how:
1. Prime the Engine
Priming the engine ensures that there’s enough fuel in the carburetor for the engine to start.
- Locate the Primer Bulb: The primer bulb is usually located on the top or side of the carburetor. It’s often a small, round bulb that you can squeeze.
- Prime the Engine: Press the primer bulb 3-5 times. This forces fuel into the carburetor.
2. Choke the Engine
The choke restricts airflow to the engine, creating a richer fuel mixture that makes it easier to start.
- Locate the Choke Lever: The choke lever is typically located on the side of the engine. It may be a lever, button, or knob.
- Engage the Choke: Push the choke lever to the “Choke” or “On” position.
3. Pull the Starter Cord
Now it’s time to get the engine going!
- Grasp the Handle: Hold the handle firmly, making sure you have a good grip.
- Pull Slowly: Pull the starter cord slowly at first, then give it a quick, strong pull.
- Repeat: If the engine doesn’t start, pull the starter cord a few more times. Make sure you’re not pulling it too fast, as this can damage the engine.
4. Release the Choke
Once the engine starts, you’ll need to release the choke gradually.
- Watch for Signs of Running: The engine may sputter or run roughly at first. Once it’s running consistently, you can slowly release the choke.
- Check the Engine Speed: The engine should idle smoothly without stalling. If it’s still running rough, you may need to adjust the choke lever slightly.
Troubleshooting Common Starting Problems
If your lawn mower won’t start, don’t panic! Here are some common issues and how to troubleshoot them:
1. No Fuel
- Check the Fuel Line: Ensure the fuel line is connected securely to the fuel tank and the carburetor.
- Check the Fuel Filter: The fuel filter may be clogged and preventing fuel from reaching the engine. Replace the fuel filter if it’s dirty.
2. Dirty Carburetor
- Clean the Carburetor: If you’ve been using old fuel, your carburetor may be gummed up. Consult your owner’s manual or a repair guide for instructions on cleaning the carburetor.
3. Spark Plug Issues
- Check the Spark Plug: The spark plug ignites the fuel mixture in the engine. If the spark plug is worn, fouled, or damaged, it won’t produce a spark and the engine won’t start.
- Replace the Spark Plug: Replace the spark plug with a new one if it’s damaged or worn.
4. Bad Battery (Electric Start Mowers)
- Check the Battery: If your mower has an electric start, check the battery terminals to ensure they are clean and secure.
- Jump Start the Battery: If the battery is weak, try jump-starting it from another battery.
- Replace the Battery: If the battery is completely dead, you’ll need to replace it.
Tips for Smooth Starting
- Keep Your Mower Clean: A clean mower is a happy mower! Remove grass clippings and debris from the engine, deck, and air filter regularly.
- Store the Mower Properly: Always store your mower with the fuel tank empty to prevent fuel from going bad.
- Read Your Owner’s Manual: Every lawn mower is different, so be sure to read your owner’s manual for specific starting instructions and troubleshooting tips.

FAQs
1. What type of lawn mower should I choose?
Choosing the right lawn mower depends on the size and terrain of your yard. If you have a small, flat lawn, a manual reel mower may be sufficient. For larger yards or uneven terrain, a gas-powered or electric mower may be better suited. Gas-powered mowers offer more power and versatility but require more maintenance. Electric mowers are quieter and more environmentally friendly but may have limited run time.
Ultimately, the best lawn mower for you depends on your individual needs and preferences. Consider the size and complexity of your lawn, your budget, and your personal comfort level with different types of mowers.
2. Do I need to use gasoline in my lawn mower?
Whether you need to use gasoline depends on the type of mower you own. Gas-powered lawn mowers, as the name suggests, require gasoline to run. Electric lawn mowers, on the other hand, run on electricity and do not need gasoline.
To determine whether your mower requires gasoline, check the owner’s manual or look for the fuel tank. If there’s a fuel tank, your mower is likely gas-powered. If there’s no fuel tank and your mower is plugged into an outlet, it’s electric.
3. What is the best type of gasoline to use in my lawn mower?
The best type of gasoline for your lawn mower is typically 87 octane unleaded gasoline. This is the most common type of gasoline available and is generally recommended by most lawn mower manufacturers. However, some newer models may require higher octane gasoline.
Always check your owner’s manual for specific fuel recommendations. Using gasoline with a lower octane rating can lead to engine knocking and performance issues, while using higher octane gasoline may not provide any benefit and could even waste money.
4. How do I prime my lawn mower?
Priming your lawn mower is a step that helps get the engine running by introducing a small amount of fuel into the carburetor. Most modern lawn mowers have an automatic choke system that eliminates the need for manual priming.
If your lawn mower has a manual choke, there will be a lever or button labeled “choke”. Pull the choke lever or press the choke button to the “on” position before starting the engine. Once the engine is running, you can slowly release the choke to allow the engine to run smoothly.
5. How do I know when my lawn mower is ready to start?
You’ll know your lawn mower is ready to start when the engine is primed and the choke is in the correct position. For most modern lawn mowers, this involves ensuring the choke is off and the fuel tank is full.
However, older models may have a priming button that needs to be pressed several times before starting. The engine should start easily and run smoothly with minimal effort. If you encounter issues starting your mower, refer to your owner’s manual for troubleshooting steps.
6. What if my lawn mower won’t start?
If your lawn mower won’t start, there are several potential reasons. First, make sure the fuel tank is full and the choke is in the correct position. If the fuel tank is empty, fill it with fresh gasoline. If the choke is in the wrong position, adjust it according to your lawn mower’s instructions.
If the mower still won’t start, check the spark plug and make sure it’s clean and properly connected. If necessary, replace the spark plug. You could also have a clogged air filter or a problem with the carburetor. If you suspect these issues, it’s best to consult your owner’s manual or seek help from a qualified mechanic.
7. How do I maintain my lawn mower?
Regular maintenance is crucial for keeping your lawn mower in top shape and extending its lifespan. This includes regular oil changes, air filter cleaning, spark plug replacement, and blade sharpening.
You should also clean the underside of the mower deck after each use to remove grass clippings and debris. Following the manufacturer’s recommendations for maintenance is essential for ensuring the safe and efficient operation of your lawn mower.
