Briggs And Stratton Lawn Mower Starts Then Dies? Find the Fix

A Briggs and Stratton lawn mower that starts then dies often has fuel or carburetor issues. Inspect the fuel supply and clean the carburetor.

Experiencing a lawn mower that starts but quickly dies can be frustrating, especially when you have yard work to complete. This common problem with Briggs and Stratton lawn mowers usually points to issues with the fuel system or the carburetor.

Ensuring your mower has fresh, clean fuel and a well-maintained carburetor can often resolve these issues. Regular maintenance, including checking the air filter and spark plug, can also prevent this problem.

Addressing these areas can help your lawn mower run smoothly and efficiently, allowing you to maintain your yard with ease. Proper care and timely troubleshooting can prolong the life of your mower.

Common Causes

Is your Briggs and Stratton lawn mower starting but then dying? Several common causes could be behind this issue. Understanding these causes can help you troubleshoot and fix the problem quickly.

Fuel Issues

Fuel-related problems are frequent culprits. Dirty or stale fuel can clog the carburetor, leading to engine stalling. Ensure you use fresh, clean gasoline.

Check the fuel filter for dirt. A clogged filter prevents fuel flow to the engine. Replace the filter if it’s dirty.

Another potential issue is the fuel cap. A faulty cap can create a vacuum inside the tank. This stops fuel from reaching the engine. Inspect the cap and replace it if needed.

Fuel Issue	Solution
Dirty or stale fuel	Use fresh gasoline
Clogged fuel filter	Replace the filter
Faulty fuel cap	Inspect and replace

Spark Plug Problems

The spark plug is vital for ignition. If it’s dirty or worn out, the engine will stall. Inspect the spark plug for any carbon deposits.

Use a spark plug cleaner to remove any buildup. If the plug is worn out, replace it with a new one.

Check the spark plug gap. A gap that’s too wide or too narrow can cause starting issues. Use a spark plug gauge to measure and adjust the gap.

• Inspect for carbon deposits
• Clean or replace the spark plug
• Check and adjust the spark plug gap

Following these steps can help keep your Briggs and Stratton lawn mower running smoothly.

First, check the fuel lines. Ensure there are no cracks or leaks. Damaged lines can restrict fuel flow.

Follow these steps to inspect the fuel lines:

1. Turn off the mower and let it cool.
2. Locate the fuel lines connected to the fuel tank and carburetor.
3. Carefully examine each line for visible damage.

Air Filter Inspection

A lawn mower that starts and then dies can be frustrating. One common issue is the air filter. A clogged air filter restricts airflow to the engine. This can cause the mower to stop running. Regular air filter inspection is essential. It ensures your mower runs smoothly.

Cleaning Techniques

First, locate the air filter on your Briggs and Stratton lawn mower. It’s usually near the engine’s top. Remove the air filter cover. Take out the filter carefully.

Check the filter for dirt and debris. Use a soft brush to clean away loose dirt. You can also use compressed air to blow off the dust. Be gentle to avoid damage.

For deeper cleaning, wash the foam filter in soapy water. Rinse thoroughly and let it dry completely. If the filter is paper, tap it gently to remove dirt. Do not wash a paper filter; it can get damaged.

Once the filter is clean, reinstall it. Make sure it’s seated properly. Replace the cover securely.

Replacement Guide

Sometimes, cleaning the air filter is not enough. If the filter is too dirty or damaged, replace it. Here’s a simple guide to help you.

1. Purchase the correct air filter for your model. Check your mower’s manual.
2. Remove the air filter cover.
3. Take out the old filter.
4. Insert the new filter. Ensure it fits snugly.
5. Replace the cover and secure it.

Replacing the air filter ensures optimal performance. It helps the engine get the right amount of air. This can prevent your mower from starting and dying. Regular maintenance saves you time and trouble.

Battery And Electrical

The battery and electrical system of your Briggs and Stratton lawn mower are crucial. A faulty battery or loose connection can cause your lawn mower to start and then die. Let’s dive into some common issues and their fixes.

Check Connections

Ensure all electrical connections are tight and free of debris. Loose or corroded wires can disrupt power flow. Check the battery terminals first.

• Inspect the battery terminals for rust or corrosion.
• Clean them with a wire brush if needed.
• Ensure the wires are tightly secured.

Next, check the spark plug wire. It should be firmly connected to the spark plug. A loose spark plug wire can cause the engine to die.

Test Battery Charge
