Understanding the Basics: Briggs & Stratton Lawn Mowers
Briggs & Stratton is a renowned brand known for its reliable and durable small engines. Their lawn mower engines are popular due to their ease of use, maintenance, and overall performance. Before diving into the starting process, let’s briefly understand the components that make up a Briggs & Stratton engine.
- Fuel Tank: Stores the fuel that powers the engine.
- Carburetor: Mixes fuel and air to create a combustible mixture.
- Spark Plug: Ignites the fuel mixture.
- Engine Cylinder: Where the combustion process takes place.
- Air Filter: Filters dust and debris from entering the engine.
- Choke: Restricts airflow to help start the engine in cold conditions.
- Starter: Used to crank the engine and start the combustion process.
Preparing Your Lawn Mower for Start-Up
Before attempting to start your Briggs & Stratton lawn mower, there are a few essential pre-start checks to ensure everything is in working order.
1. Fuel and Oil Level Check
- Fuel: Start by inspecting the fuel tank. If the fuel is old, stale, or below the recommended level, top it off with fresh, clean gasoline. Always refer to your mower’s manual for the recommended fuel type and octane rating.
- Oil: Check the oil level using the dipstick. Ensure the oil is at the appropriate level, and if necessary, top it off with the recommended oil type.
2. Inspect the Spark Plug
- Condition: Remove the spark plug and visually inspect it. The electrode should be clean and free of any debris or buildup. If it’s worn or damaged, replace it with a new one.
- Gap: Use a spark plug gap tool to check the gap between the electrode and the center electrode. Adjust it according to the manufacturer’s specifications.
3. Air Filter Check
- Cleanliness: Remove the air filter and inspect it. If it’s dirty or clogged, clean it with a brush and compressed air or replace it with a new one. A clean air filter ensures proper airflow to the engine.
4. Battery Connection (For Electric Start Mowers)
- Battery: For mowers with electric start, ensure the battery is fully charged and the battery terminals are clean and secure. If the battery is weak or dead, recharge it or replace it with a new one.
Starting Your Briggs & Stratton Lawn Mower: Step-by-Step
Now that you’ve performed all the necessary pre-start checks, you’re ready to fire up your mower.
1. Set the Choke (If Required)
- Cold Engine: If your mower hasn’t been running recently or it’s a cold day, engage the choke. This restricts airflow, enriching the fuel mixture, making it easier to start.
- Warm Engine: If the engine is warm, the choke is usually not required.
2. Prime the Engine (If Necessary)
- Manual Priming: Some Briggs & Stratton models have a priming bulb. Pump it a few times to send fuel to the carburetor. This helps start the engine quickly.
- Automatic Priming: Newer models often have an automatic priming system, eliminating the need for manual priming.
3. Engage the Starter
- Pull-Start: For pull-start mowers, firmly grasp the recoil handle and pull it sharply. If the engine doesn’t start on the first pull, continue pulling until it starts.
- Electric Start: If your mower has electric start, turn the key to the start position. The engine should crank and start.
4. Disengage the Choke
- Warm Engine: Once the engine is running, slowly disengage the choke. This allows more air to enter the carburetor, preventing the engine from stalling.
5. Allow the Engine to Warm Up
- Idle: Let the engine run at idle speed for a few minutes to allow it to warm up and stabilize.
Troubleshooting Common Starting Problems
If your Briggs & Stratton lawn mower is having trouble starting, here are some common issues and how to troubleshoot them:
- No Spark: Check the spark plug wiring and connection. If the spark plug is faulty, replace it with a new one.
- Fuel Issues: Ensure the fuel tank is filled with fresh gas and the fuel lines are free of any clogs.
- Clogged Air Filter: A dirty air filter restricts airflow, making starting difficult. Clean or replace the air filter.
- Low Oil Level: A low oil level can cause engine damage. Top off the oil level.
- Flooded Engine: If you’ve pulled the starter cord several times and the engine hasn’t started, the carburetor may be flooded. Try the following:
- Remove the spark plug and crank the engine a few times to clear out any excess fuel.
- Replace the spark plug and try starting the engine again.
Important Safety Tips
- Safety Glasses: Always wear safety glasses when working around lawn mowers.
- Gloves: Wear gloves to protect your hands from cuts or scrapes.
- Clear the Area: Remove any debris or obstacles from the mowing area.
- Fuel Handling: Always handle gasoline with care. Never refuel a hot engine, and keep the fuel away from open flames.
- Children and Pets: Keep children and pets away from the lawn mower when it’s running.

2. What are the essential safety precautions before starting a Briggs & Stratton lawn mower?
Before starting any gasoline-powered lawn mower, it’s important to take essential safety precautions. Firstly, always wear safety glasses and sturdy shoes. This protects your eyes and feet from potential debris. Secondly, ensure the area around the mower is clear of obstacles and people. A clear work area minimizes the risk of accidents. Additionally, it’s important to check the fuel level and ensure that the mower is on a stable and level surface before starting it.
By adhering to these safety precautions, you can significantly reduce the risk of injury to yourself and others while operating a lawn mower. Remember, safety should always be your top priority when working with machinery.
3. What is the procedure for checking the oil level in a Briggs & Stratton lawn mower?
Checking the oil level in your Briggs & Stratton lawn mower is crucial for its longevity. Start by locating the dipstick, which is usually near the engine. Pull the dipstick out and wipe it clean with a rag. Then, reinsert the dipstick fully and pull it out again. The oil level should be between the “Full” and “Low” marks on the dipstick. If the oil level is low, add more oil until it reaches the “Full” mark.
Regular oil checks ensure that your engine is properly lubricated and prevent damage caused by low oil levels. It’s important to use the correct type of oil recommended in your owner’s manual.
4. How do I prime a Briggs & Stratton lawn mower?
Priming a Briggs & Stratton lawn mower is essential to ensure proper fuel delivery to the engine, especially when starting it for the first time after storage or when the fuel tank has been emptied. To prime the mower, locate the primer bulb, typically situated near the carburetor. Press the primer bulb several times until it becomes firm, which indicates that the carburetor is full of fuel.
This priming process ensures that there’s enough fuel in the carburetor for the engine to ignite and start smoothly. However, avoid over-priming, as it can lead to flooding the engine.
5. How do I start a Briggs & Stratton lawn mower with a choke?
Starting a Briggs & Stratton lawn mower with a choke involves a simple procedure. First, locate the choke lever, which is usually situated near the engine. Move the choke lever to the “Choke” position, which restricts airflow and allows for a richer fuel mixture for easier starting.
Next, pull the starter cord firmly and quickly. Once the engine starts, slowly move the choke lever back to the “Run” position. This gradual process allows the engine to adjust to the normal fuel mixture and prevent stalling.
6. How do I stop a Briggs & Stratton lawn mower?
Stopping a Briggs & Stratton lawn mower is a simple process. Firstly, locate the stop switch, usually a red button or lever positioned on the handle. Press the stop switch, which will immediately shut off the engine.
It’s important to wait for the engine to fully stop before handling the mower or refuelling. Additionally, always ensure that the mower is in a safe and level position before stopping it.
7. What are some troubleshooting tips for Briggs & Stratton lawn mowers?
If your Briggs & Stratton lawn mower isn’t starting, there are several troubleshooting steps you can take. Firstly, check the fuel level and ensure it’s not empty. Secondly, inspect the spark plug for any signs of damage or corrosion.
If the engine is flooded, allow it to air out for a few minutes before trying to start it again. If the problem persists, it’s best to consult your owner’s manual or contact a qualified mechanic for assistance.
By following these troubleshooting tips, you can often identify and resolve common issues with your Briggs & Stratton lawn mower. Remember, regular maintenance and timely repairs can help prevent more serious problems down the road.
