Have you ever tried to start your lawn mower only to find it sputtering and stalling? Bad gas can be a real headache, especially when you’re itching to tackle that overgrown yard. It’s a common issue that can leave you frustrated and your lawn looking neglected.
Key Takeaways
- Understanding Bad Gas: Bad gas can cause lawn mowers to sputter and stall, often due to age, ethanol content, or contaminated storage.
- Signs of Bad Gas: Difficulty starting, sputtering engines, reduced power, and frequent stalling are common indicators of bad gas.
- Removing Bad Gas: Use a fuel siphon to drain bad gas, clean the tank, inspect fuel lines, and refill with fresh fuel to restore mower performance.
- Preventing Future Issues: Use fuel stabilizers, store gasoline in proper containers in cool, dry conditions, and keep containers sealed to prevent contamination.
- Choosing the Right Fuel: Opt for ethanol-free gasoline or at least mid-grade options to minimize the risk of performance issues related to fuel quality.
Understanding Bad Gas
Bad gas can disrupt your lawn mower’s performance, causing sputtering and stalling. Recognizing its causes and signs helps you take appropriate action promptly.
Causes of Bad Gas in Lawn Mowers
- Age of Fuel: Gasoline degrades over time. Fuel older than 30 days may contain moisture and contaminants.
- Ethanol Content: Many fuels contain ethanol. Ethanol attracts water, leading to phase separation, which can clog fuel lines and filters.
- Poor Storage Conditions: Storing gas in hot places can accelerate its degradation. Sunlight exposure also contributes to its breakdown.
- Contaminated Fuel: Fuel stored in unclean containers may include dirt or debris. This can pollute your mower’s fuel system.
- Difficulty Starting: If your mower struggles to start or takes several attempts, bad gas might be the reason.
- Sputtering Engine: A mower that sputters while running indicates inconsistent fuel flow, often due to bad gas.
- Reduced Power: If your mower underperforms or lacks power during operation, it may be struggling with contaminated fuel.
- Frequent Stalling: Consistent stalling during mowing points to fuel quality issues. If it stops frequently, bad gas is likely at fault.
How to Remove Bad Gas from a Lawn Mower
Removing bad gas from a lawn mower is essential for restoring its performance. Follow these steps to ensure a clean process.
Tools Needed for the Task
- Fuel siphon: Used for safely draining gas without spills.
- Fuel container: Must be sealed to store the old gas.
- Wrench set: Necessary for removing the fuel line if needed.
- Shop towel: Helps clean up any spills.
- Safety gloves: Protects your hands from chemicals.
- Prepare your workspace: Clear the area around the mower. Ensure there’s good ventilation.
- Turn off the mower: Ensure the engine is cool. Disconnect the spark plug for safety.
- Use the fuel siphon: Place the siphon tube into the gas tank. Squeeze the pump and let the bad gas flow into the fuel container.
- Dispose of old gas: Take the filled container to a proper disposal site. Don’t pour it down the drain.
- Inspect the fuel line: If gas remains, unclip the fuel line using a wrench. Drain any remaining fuel into the container.
- Clean the tank: Wipe the inside of the tank with a shop towel to remove residue.
- Refill with fresh gas: Fill the tank with high-quality, fresh fuel. This helps prevent future issues.
- Reconnect everything: Replace the fuel line and reconnect the spark plug.
- Test the mower: Start the mower to check if it runs smoothly. If not, further cleaning of the carburetor may be necessary.
These straightforward steps make removing bad gas quick and efficient, readying your mower for optimal performance.
Preventing Bad Gas in the Future
Preventing bad gas in your lawn mower is crucial for maintaining its performance. Following a few best practices ensures you avoid issues down the road.
Best Practices for Fuel Storage
- Use Fuel Stabilizers: Add fuel stabilizer when storing gas for longer than 30 days. This helps prevent fuel breakdown and keeps it fresh.
- Store in Proper Containers: Use clean, approved containers designed for fuel storage. Avoid using old or contaminated containers that might introduce impurities.
- Keep It Cool and Dry: Store fuel in a shaded, cool area to reduce evaporation and degradation. Heat and light can cause the fuel to break down faster.
- Seal Containers Tightly: Ensure containers are tightly sealed to prevent moisture and contaminants from entering.
- Ethanol-Free Gasoline: This type of fuel provides the best performance and minimizes the risk of fuel system issues. Look for it at specific fuel stations or purchase from specialty retailers.
- Mid-Grade or Premium Gasoline: If ethanol-free is unavailable, opt for mid-grade or premium gasoline. These typically contain less ethanol than regular unleaded.
- Regular Unleaded Gasoline: If other options are not accessible, you can use regular unleaded, but keep an eye on storage duration to prevent issues.
Implementing these strategies ensures your lawn mower runs efficiently and avoids the frustrations caused by bad gas.
Conclusion
Dealing with bad gas in your lawn mower can be a hassle but it doesn’t have to keep you from achieving a well-manicured lawn. By following the steps to drain and clean your mower you’ll have it running smoothly in no time.
Remember to take preventive measures to keep bad gas at bay. With a little care in how you store your fuel and choosing the right type, you can enjoy a reliable mower that starts easily and performs well.
Happy mowing and may your yard always look its best!
