Spring has sprung, and that means it’s time to get your lawn mower out of storage and ready for action. But what do you do if you’re facing a stubborn Briggs and Stratton 500 series mower that just won’t start? Don’t worry, this article will guide you through the process, from basic troubleshooting to more advanced solutions, ensuring you’re back to mowing your lawn in no time. We’ll cover everything from checking fuel and spark to identifying common problems and their fixes, so you can confidently tackle any starting issues.
Starting a Briggs and Stratton 500 series lawn mower isn’t as complicated as it might seem. It generally involves a few basic steps like ensuring there’s fuel, checking the spark plug, and making sure the engine is in the “on” position. This article will go into more detail about each step and provide troubleshooting tips for common starting problems.
Getting Ready to Start: Essential Pre-Checks
Before jumping into the actual starting process, there are a few essential checks you should perform to ensure your mower is ready to go:
1. Fuel Level Check:
- H3: Is it empty? Make sure your mower has enough fuel. If it’s running low, fill the tank. Briggs and Stratton 500 series mowers typically use regular unleaded gasoline.
- H3: Is it old? If you’ve had fuel in the tank for a while, it’s best to drain it and replace it with fresh fuel. Old fuel can gum up the engine and cause starting problems.
2. Spark Plug Inspection:
- H3: Location, Location, Location: The spark plug is usually located on the top of the engine, near the cylinder head. It’s often covered by a spark plug wire boot.
- H3: Visual Check: Visually inspect the spark plug. Look for signs of wear, corrosion, or fouling. If it looks dirty or damaged, replace it.
3. Choke Position:
- H3: Understand the Choke: The choke helps to enrich the fuel mixture for easier starting, especially in cold weather. Most Briggs and Stratton 500 series mowers have a choke lever located on the engine.
- H3: Position it Correctly: Before starting, make sure the choke lever is in the “choke” position, which is usually indicated by a symbol or “choke” label.
Starting Your Briggs and Stratton 500 Series Mower: The Steps
With the pre-checks done, you’re ready to start your mower. Here’s a step-by-step guide:
- Check the Engine’s On/Off Switch: Ensure the engine switch is in the “on” position. It’s usually a toggle switch located on the handle or near the engine.
- Prime the Engine (If Necessary): Some Briggs and Stratton 500 series mowers have a primer bulb. If yours does, press it several times to send fuel to the carburetor.
- Engage the Choke: If your engine is cold or the weather is chilly, engage the choke lever.
- Pull the Starter Cord: Slowly pull the starter cord out until you feel resistance, then give it a firm pull. Avoid yanking it violently, as this can damage the starter mechanism.
- Disengage the Choke (Once the Engine Starts): Once the engine starts, gradually disengage the choke lever. You’ll hear the engine speed increase as the choke is released.
Troubleshooting Common Starting Problems:
Even with the right steps, your Briggs and Stratton 500 series mower might still refuse to start. Here are some common problems and how to fix them:
1. No Spark
- H4: Test the Spark Plug: Disconnect the spark plug wire from the spark plug. Hold the spark plug against a grounded metal object, like the engine block, and pull the starter cord. If there is a spark, the problem lies elsewhere. If there is no spark, you need to troubleshoot the ignition system.
- H4: Check the Spark Plug Wire: Inspect the spark plug wire for cracks or damage. If you find any issues, replace the wire.
- H4: Inspect the Ignition Coil: The ignition coil is responsible for generating the spark. Check for any signs of damage or loose connections. If necessary, replace the ignition coil.
2. Fuel Problems
- H4: Check the Fuel Line: Inspect the fuel line for any cracks or blockages. Replace the fuel line if necessary.
- H4: Inspect the Fuel Filter: The fuel filter prevents debris from entering the carburetor. Check the filter for clogging and replace it if needed.
- H4: Clean the Carburetor: A dirty carburetor can prevent fuel from reaching the engine. You can clean it yourself or take it to a professional for servicing.
3. Engine Issues
- H4: Check for Engine Compression: If the engine lacks compression, it won’t start. This can be caused by a worn-out piston or rings. A compression test will help determine if this is the problem.
- H4: Examine the Valves: Valve issues can also cause starting problems. Make sure the valves are properly adjusted and functioning correctly.
Beyond the Basics: Tips for Success
Here are a few additional tips to help you get your Briggs and Stratton 500 series mower running smoothly:
- H4: Regular Maintenance: Regular maintenance is crucial for ensuring your mower starts reliably. Change the oil and air filter regularly, and check the spark plug and fuel filter at least once a season.
- H4: Fuel Additives: Use a fuel stabilizer in your gasoline to prevent it from going bad, especially if you’re storing the mower for a prolonged period.
- H4: Battery Maintenance: If your mower has an electric start, ensure the battery is fully charged before trying to start it.
- H4: Seek Professional Help: If you’re still having trouble starting your mower, it’s best to seek professional help. A qualified mechanic can diagnose and repair any complex issues.
