Common Reasons For Starting Issues
When a Briggs and Stratton lawn mower won’t start, several common factors could be the cause. Below are key issues to check.
Fuel Problems
Fuel issues often lead to starting difficulties. Old or stale fuel can prevent proper engine operation. Use fresh gasoline, ideally less than 30 days old. If fuel is bad, drain the tank and refill it with new gas. Also, check for blockages in the fuel line. A clogged fuel filter can restrict fuel flow, creating starting problems.
Spark Plug Issues
Spark plug problems can also hinder starting. Inspect the spark plug for wear and deposits. A worn or dirty spark plug may fail to generate a spark. Clean or replace the spark plug as necessary. Ensure the gap between the electrodes is correct, ideally around 0.030 inches. A faulty spark plug can cause starting issues, even if other components function properly.
Air Filter Blockage
A blocked air filter can restrict airflow to the engine, leading to starting issues. Check the air filter for dirt or debris. Clean or replace it if the filter is dirty. A clean filter allows the engine to breathe, promoting efficient combustion. Regular air filter maintenance improves overall mower performance and starting reliability.
Troubleshooting Steps
If your Briggs and Stratton lawn mower won’t start, follow these troubleshooting steps to identify and fix the issue effectively.
Checking the Fuel System
Check for fresh gasoline in the tank. Old fuel can lose its potency and cause starting problems. Drain any stale gasoline and replace it with fresh fuel. Ensure the fuel lines are free from clogs. Inspect the fuel filter for dirt or debris that may obstruct fuel flow. Clean or replace it if necessary.
Inspecting the Spark Plug
Inspect the spark plug for wear or damage. Remove the spark plug and examine its condition. Look for carbon buildup or corrosion. If the electrode is worn down, replace the spark plug. Ensure the gap between the electrodes matches the manufacturer’s specifications. Reinstall the spark plug securely.
Evaluating the Battery Condition
Evaluate the battery’s condition if your mower has an electric start. Check for corrosion on the battery terminals. Clean any corrosion with a mixture of baking soda and water. Verify the battery voltage; a fully charged battery should read around 12.6 volts. If the voltage is low, recharge or replace the battery as needed.
Preventive Maintenance Tips
Maintaining your Briggs and Stratton lawn mower prevents starting issues, ensuring reliable performance. Follow these tips to keep your mower in great condition.
Regular Cleaning
Keep your mower clean to enhance its efficiency. Clean the exterior to remove grass clippings and dirt. Focus on critical areas:
- Air Filter: Remove and rinse the air filter every 25 hours of use. Replace it if it’s too dirty.
- Cutting Deck: Scrape off grass build-up after each use. A clean deck promotes better cutting.
- Fuel System: Inspect the fuel system. Remove any debris from the fuel cap and tank. This practice prevents clogs.
Seasonal Preparations
Prepare your mower for changing seasons. Adjustments during seasonal transitions enhance performance:
- Spring Preparation: Start the season with fresh gasoline. Drain old fuel and replace it with fresh fuel mixed with a fuel stabilizer.
- Summer Tune-Up: Check spark plugs and replace them if worn. Clean or replace the air filter to maintain airflow.
- Fall Storage: Prepare for winter by running the mower until the fuel tank is empty. This step prevents fuel degradation over extended storage.
Proper Storage Techniques
Store your mower correctly to protect it from damage. Follow these storage practices:
- Clean Thoroughly: Clean the mower before storing it to prevent rust and corrosion.
- Dry Location: Store your mower in a dry, covered area. Avoid exposure to moisture, which leads to rust.
- Off-Season Checks: Regularly check the battery and fuel system while in storage. This practice ensures everything remains functional for the next use.
Using these preventive maintenance tips keeps your Briggs and Stratton lawn mower running smoothly. Taking proactive steps ensures hassle-free operation every mowing season.
