The warm weather has arrived, and your lawn is starting to look a little shaggy. You pull your trusty Briggs and Stratton lawn mower out of the shed, ready to tackle the task, but… it’s not starting. Panic sets in! Don’t worry, you’re not alone. Many lawn mower owners find themselves staring at a stubborn engine, wondering where to begin. This guide will walk you through the simple steps of turning on your Briggs and Stratton lawn mower, so you can get back to enjoying a perfectly manicured lawn.
In this article, we will cover the basics of starting a Briggs and Stratton lawn mower, including:
- Understanding the different types of starts
- Preparing the mower for operation
- Troubleshooting common starting problems
Understanding the Types of Starts
Briggs and Stratton lawn mowers typically use one of two starting methods: recoil start or electric start.
- Recoil start: This classic method uses a pull cord to crank the engine. It’s typically found on older or more basic models.
- Electric start: This modern method utilizes a battery and starter motor to turn the engine over, making starting easier. Look for a key ignition switch on your mower if it has electric start.
Preparing the Mower for Operation
Before you even try to start your mower, take a few minutes to prepare it. This simple step can save you a lot of frustration:
- Check the fuel level: Your mower needs fuel to run, so make sure the tank is filled. Using fresh gasoline is always recommended, as older fuel can gum up the engine.
- Check the oil level: Your mower engine needs oil to lubricate moving parts. Consult your owner’s manual to locate the dipstick and check the oil level. Top it off if necessary.
- Make sure the blades are sharp: Dull blades will leave a ragged cut and strain the engine. Sharpen your blades or replace them if necessary.
- Check for any obstructions: Look around the mower deck, engine, and under the chassis for any debris or obstacles that might prevent it from running smoothly.
Starting a Recoil Start Mower
Once your mower is prepped, you’re ready to start it!
- Set the choke: This lever, often located near the engine, enriches the fuel mixture for easier starting. Check your owner’s manual for the specific choke position for your model.
- Prime the carburetor: Some recoil start mowers have a primer bulb. Press it several times to fill the carburetor with fuel.
- Position the blade control lever: Make sure this lever is in the “off” or “disengage” position to prevent the blades from spinning while you’re starting the engine.
- Pull the recoil cord: Hold the handle firmly and pull the cord with a steady, strong motion. Don’t jerk or yank it. You may need to pull several times before the engine catches.
- Release the choke: Once the engine starts, gradually release the choke lever until the engine runs smoothly.
Starting an Electric Start Mower
If your mower has electric start, the process is even simpler:
- Turn the key to the “on” position: This will engage the ignition system.
- Position the blade control lever: As with the recoil start, make sure this lever is in the “off” or “disengage” position.
- Press the start button: The engine should crank and start.
- Release the start button: The engine should continue running.
Troubleshooting Common Starting Problems
Even if you follow these steps, your lawnmower might still refuse to cooperate. Here are some common starting problems and their solutions:
1. The Engine Won’t Turn Over
- Problem: The battery is dead, or the starter motor is faulty.
- Solution: Check the battery terminals for corrosion and clean them if necessary. If the battery is old or weak, replace it. If the starter motor is faulty, you may need to contact a repair shop.
2. The Engine Sputters and Dies
- Problem: The carburetor is clogged or the fuel is old.
- Solution: Clean the carburetor with a carburetor cleaner kit. Drain the fuel tank and refill it with fresh gasoline.
3. The Engine Runs for a Short Time Then Stops
- Problem: The spark plug is fouled or the ignition system is faulty.
- Solution: Remove the spark plug and clean it with a wire brush. If it’s severely worn, replace it. If the ignition system is faulty, you may need to contact a repair shop.
4. The Engine Runs But Doesn’t Cut
- Problem: The blade clutch is faulty, the blades are dull, or the safety interlock system is malfunctioning.
- Solution: Check the blade clutch for signs of wear or damage. Replace it if necessary. Sharpen or replace the blades. Inspect the safety interlock system for any broken wires or connections.
Additional Tips for Starting Your Lawn Mower
- Read your owner’s manual: The best resource for starting your specific lawn mower is the owner’s manual. It will contain detailed instructions and troubleshooting tips.
- Use fresh fuel: Older gasoline can gum up the engine and prevent it from starting. Use fresh fuel and store it in a clean, sealed container.
- Keep your mower clean: Dust, dirt, and debris can interfere with the engine’s performance. Regularly clean your mower to prevent these problems.
- Don’t force the recoil cord: If you pull the cord several times and it doesn’t start, stop and troubleshoot the problem. Forcing the cord can damage the engine.
- Consult a professional: If you’re unable to troubleshoot the problem yourself, contact a qualified lawn mower repair shop.

FAQs
Q1: What type of Briggs and Stratton lawn mower do I have?
A: There are two main types of Briggs and Stratton lawn mowers: push mowers and riding mowers. Push mowers are manual and require you to push them around your lawn, while riding mowers are powered by a gasoline engine and have a seat for the operator. To determine which type you have, simply look at the machine. If you see a seat, it’s a riding mower. If it’s just a deck with wheels, it’s a push mower.
Q2: How do I find the choke lever on my Briggs and Stratton lawn mower?
A: The choke lever is typically located on the top or side of the engine. It may be labeled with the word “choke” or have a symbol of a hand making a choking motion. To find it, you may need to consult your owner’s manual or search online for your specific model number.
Q3: What is the purpose of the choke lever?
A: The choke lever restricts airflow to the engine, allowing for a richer fuel-air mixture. This is necessary to start a cold engine because the fuel doesn’t vaporize as easily at lower temperatures. Once the engine starts, you can gradually release the choke lever to allow for more airflow.
Q4: What is the best way to start a Briggs and Stratton lawn mower?
A: The best way to start a Briggs and Stratton lawn mower is to follow these steps:
- Engage the choke lever: This will help the engine start by creating a richer fuel-air mixture.
- Pull the starter cord: Pull the cord firmly and quickly until the engine starts.
- Release the choke lever gradually: Once the engine is running, you can gradually release the choke lever to allow for more airflow.
- Disengage the choke lever completely: After the engine is warm, disengage the choke lever completely.
Q5: How do I know if my Briggs and Stratton lawn mower is running properly?
A: A properly running Briggs and Stratton lawn mower will have a smooth, consistent idle and will be able to maintain its speed without stalling. The engine should not be smoking excessively or making any unusual noises. If you notice any problems, consult your owner’s manual or a qualified mechanic.
Q6: What if my Briggs and Stratton lawn mower won’t start?
A: If your Briggs and Stratton lawn mower won’t start, there are a few things you can try:
- Make sure the gas tank is full: An empty gas tank will prevent the engine from starting.
- Check the spark plug: A fouled or damaged spark plug can prevent the engine from igniting.
- Check the air filter: A dirty air filter can restrict airflow to the engine, preventing it from starting.
- Check the fuel lines and carburetor: A blockage in the fuel lines or carburetor can prevent fuel from reaching the engine.
Q7: What should I do if my Briggs and Stratton lawn mower is running rough?
A: If your Briggs and Stratton lawn mower is running rough, there are a few things you can check:
- Check the spark plug: A fouled or worn-out spark plug can cause the engine to run poorly.
- Check the air filter: A dirty air filter can restrict airflow to the engine, causing it to run rough.
- Check the carburetor: A dirty or malfunctioning carburetor can cause the engine to run poorly.
- Check the fuel lines: Blockages in the fuel lines can prevent fuel from reaching the engine, causing it to run rough.
