The sweet smell of freshly cut grass – a sign of a beautiful summer day. But what happens when your trusty lawnmower refuses to start? The culprit could be bad gas. That stale, aged fuel can cause all sorts of problems, from sputtering to complete engine failure. But don’t despair! This comprehensive guide will equip you with the knowledge and steps to effectively remove bad gas from your lawnmower, get it running smoothly, and back to mowing your green paradise. We’ll cover everything from identifying the signs of bad gas to proper draining procedures, including tips for preventing future fuel woes.
Identifying Bad Gas: A Quick Check
The telltale signs of bad gas are often easy to spot. The fuel will appear discolored, with a dark, almost brownish hue instead of the usual clear, amber color. A strong, pungent odor is another giveaway. If your lawnmower struggles to start or sputters and dies, bad gas is likely the culprit.
The Importance of Fresh Fuel
Using fresh, high-quality gasoline is crucial for optimal lawnmower performance and longevity. Gasoline degrades over time, losing its volatility and becoming harder to ignite. This leads to poor combustion, decreased power, and ultimately, engine damage.
Draining the Fuel Tank: The Essential First Step
Before you begin, take safety precautions:
- Wear safety glasses and gloves to protect your eyes and hands.
- Work in a well-ventilated area, away from open flames or sparks.
- Always disconnect the spark plug to prevent accidental ignition.
Step-by-Step Guide to Draining the Fuel Tank:
- Locate the Fuel Tank: The fuel tank is typically located on the side or top of the mower.
- Turn off the Fuel Valve: Locate the fuel valve (usually a lever or knob) and turn it to the “off” position to prevent fuel from flowing into the carburetor.
- Remove the Fuel Cap: Carefully unscrew the fuel cap.
- Prepare a Container: Have a clean, sealable container ready to collect the old fuel. A glass jar or plastic jug with a lid works well.
- Drain the Fuel Tank: Tilt the mower over the container, allowing the fuel to drain out of the tank.
- Repeat Draining: Once the fuel has stopped draining, tilt the mower in a different direction to ensure all the fuel is removed.
Cleaning the Fuel System: A Deeper Clean
Cleaning the Fuel Lines:
- Disconnect the Fuel Lines: Carefully disconnect the fuel lines that run from the tank to the carburetor.
- Clean the Fuel Lines: Use a small brush or a piece of wire to clear any debris or sediment from the inside of the fuel lines.
- Blow Out the Lines: Use compressed air to blow out the lines, removing any remaining particles.
- Reconnect the Fuel Lines: Carefully reconnect the fuel lines to the tank and carburetor.
Cleaning the Carburetor:
- Remove the Carburetor: Locate the carburetor on the engine and carefully remove it. Consult your lawnmower’s manual for specific instructions.
- Disassemble the Carburetor: Using a small screwdriver or wrench, carefully disassemble the carburetor into its individual components.
- Clean the Components: Clean each component thoroughly with carburetor cleaner, using a brush or compressed air to remove any debris.
- Inspect the O-Rings: Inspect the O-rings for wear or damage and replace them if necessary.
- Reassemble the Carburetor: Carefully reassemble the carburetor, ensuring all parts are properly seated.
- Install the Carburetor: Install the carburetor back onto the engine, making sure all connections are secure.
Preventing Future Fuel Problems
Using Fuel Stabilizer:
- Fuel stabilizers are designed to prevent fuel degradation and extend its shelf life.
- Add fuel stabilizer to your gasoline tank following the manufacturer’s instructions.
- Stabilized gas can be stored for longer periods without significant degradation.
Storing Your Lawn Mower Properly:
- When storing your lawnmower for extended periods, drain the fuel tank completely.
- Run the engine until it stops to clear any fuel remaining in the lines.
- Store the lawnmower in a dry, well-ventilated area.
Conclusion:
Dealing with bad gas in your lawnmower can be frustrating, but it’s a common issue that can be resolved with proper maintenance. By following these steps, you can successfully remove bad gas, clean your fuel system, and prevent future fuel-related problems. Remember, fresh fuel is essential for optimal performance and a longer lifespan for your lawnmower. With a little effort, you can keep your mower running smoothly and enjoy a beautifully manicured lawn all season long.
FAQ
How long does bad gas last in a lawnmower?
Gasoline can last for a long time if it’s stored correctly. But if it’s not stored correctly, it can start to degrade and lose its power within just a few months. Factors like humidity, temperature, and exposure to sunlight can affect the rate of degradation. Even if you’re storing gasoline properly, it’s not recommended to use it in a lawnmower after a year.
What are the signs of bad gas in a lawnmower?
There are a few signs that your lawnmower has bad gas. The engine might sputter or struggle to start. The mower might also run poorly or smoke excessively. If you see any of these signs, it’s a good idea to drain the gas tank and refill it with fresh fuel.
How to drain the gas tank on a lawnmower?
Draining the gas tank on a lawnmower is a simple process. First, you’ll need to find the drain plug. It’s usually located at the bottom of the tank. Once you’ve found the drain plug, you can remove it and let the gas drain into a container. Make sure to do this in a well-ventilated area.
