The sweet smell of freshly cut grass, the warm sunshine on your face, and the satisfying hum of your Craftsman riding lawn mower – it’s the perfect recipe for a relaxing summer afternoon. But what happens when that hum turns into a sputtering cough, leaving you stranded in your yard? A common culprit for a lawn mower that won’t start is a lack of fuel. This is where starter fluid comes in, a temporary solution to get your mower running again. But where exactly do you spray this magic elixir to bring your Craftsman back to life? This article will walk you through the process, providing essential tips and safety precautions to ensure a smooth restart.
Overview:
Spraying starter fluid directly into the carburetor of your Craftsman riding lawn mower is the most effective way to get it running. However, this method should only be used as a last resort, as starter fluid is highly flammable and can damage your engine if used excessively.
Locating the Carburetor on Your Craftsman Riding Lawn Mower
The first step in using starter fluid is locating the carburetor, the heart of your mower’s engine that mixes fuel and air. The carburetor is usually situated on the top or side of the engine, near the air filter.
Identifying the Carburetor:
- Look for a cylindrical metal object: The carburetor will typically have a round or rectangular shape and may be made of metal or plastic.
- Spot the air filter: The air filter is usually attached to the carburetor, and it helps clean the air entering the engine.
- Check for fuel lines: Look for fuel lines connecting to the carburetor, indicating the fuel intake point.
Finding the Carburetor on Different Craftsman Models:
- Craftsman Riding Lawn Mowers with Briggs & Stratton Engines: The carburetor is often located on the side of the engine, near the air filter. It may be hidden under a small metal cover or shield.
- Craftsman Riding Lawn Mowers with Kohler Engines: Kohler engines usually have the carburetor positioned on top of the engine, near the air filter. It may be easily accessible or slightly concealed by other components.
Using Starter Fluid Safely and Effectively:
Once you’ve located the carburetor, you’re ready to use starter fluid. Here’s how to do it safely and effectively:
Safety Precautions:
- Use a well-ventilated area: Ensure there is plenty of fresh air circulation to prevent the build-up of flammable fumes.
- Keep away from open flames: Avoid using starter fluid near any potential sources of ignition, including lighters, cigarettes, or sparks.
- Wear protective gear: Use safety glasses and gloves to protect your eyes and skin from potential splashes.
Applying Starter Fluid:
- Turn off the engine and ignition: Make sure the engine is completely off and the ignition switch is turned to the “off” position.
- Locate the carburetor’s intake: Look for a small hole or opening near the carburetor’s body.
- Spray a short burst of starter fluid: Gently spray a small amount of starter fluid into the carburetor’s intake, avoiding excessive spraying.
- Try starting the engine: Turn the key and try to start the engine. The starter fluid should help ignite the fuel, allowing the engine to start.
- Don’t overuse starter fluid: If the engine doesn’t start after a few tries, don’t keep spraying. Overuse can damage the engine and create safety risks.
Troubleshooting: Why Your Craftsman Riding Lawn Mower Won’t Start
If you’ve followed the steps above and your Craftsman riding lawn mower still won’t start, there may be other underlying issues. Here are some common causes and troubleshooting steps:
Fuel Problems:
- Empty Fuel Tank: Ensure your fuel tank has enough gasoline.
- Clogged Fuel Filter: A clogged fuel filter can restrict fuel flow to the engine. Inspect and replace the filter if necessary.
- Old or Bad Fuel: Old gasoline can lose its potency and become unusable. Drain the old fuel and refill with fresh gasoline.
Engine Problems:
- Spark Plug Issues: A faulty or dirty spark plug can prevent the engine from igniting. Inspect and clean or replace the spark plug.
- Air Filter Clogging: A dirty air filter restricts airflow, affecting the engine’s performance. Clean or replace the air filter.
Important Considerations
- Starter fluid is a temporary solution: It’s not intended to be a long-term fix for a stubborn engine.
- Professional help may be necessary: If your Craftsman lawn mower consistently fails to start, even after troubleshooting, it’s best to seek professional help.

Frequently Asked Questions
1. What is starter fluid and why do I need it?
Starter fluid, also known as ether, is a highly flammable liquid that assists in starting engines that are having trouble igniting. It’s often used when cold weather makes it difficult for the engine to fire. When sprayed into the carburetor, starter fluid vaporizes quickly, creating a highly combustible mixture that ignites easily, helping the engine start.
While starter fluid can be a lifesaver in cold weather, it should be used sparingly. Excessive use can damage the engine and should be avoided.
2. Where exactly do I spray starter fluid on my Craftsman riding lawnmower?
The location for spraying starter fluid on your Craftsman riding lawnmower depends on the model. However, the general location is the carburetor. Look for a small, round opening on the carburetor, often with a rubber cap or gasket. This is the intake manifold, and spraying starter fluid directly into this opening will help ignite the fuel.
If you can’t locate the carburetor, consult your owner’s manual for specific instructions on your model. You can also consult your local hardware store or a mechanic for assistance.
3. Can I spray starter fluid in the air intake of my Craftsman riding lawnmower?
Spraying starter fluid directly into the air intake of your Craftsman riding lawnmower is not recommended. This is because the air intake is designed to draw air into the engine for combustion. Spraying starter fluid into the intake can cause the engine to run too fast or even backfire.
Instead, you should aim for the carburetor where the fuel and air mix before entering the engine. This ensures that the starter fluid is properly distributed for efficient ignition.
4. How much starter fluid should I use?
The amount of starter fluid needed will vary depending on the size of your Craftsman riding lawnmower’s engine and the temperature. However, a short burst of 1-2 seconds is usually sufficient.
Using too much starter fluid can lead to engine damage and should be avoided. It’s also important to remember that starter fluid is highly flammable, so handle it with caution and always follow the instructions on the product label.
5. How often can I use starter fluid?
Starter fluid should only be used as a last resort and only when absolutely necessary. Frequent use can damage your engine’s components and should be avoided.
If your Craftsman riding lawnmower is consistently having trouble starting, it’s better to have it serviced by a professional mechanic. They can diagnose and address any underlying issues that may be preventing your mower from starting properly.
6. Is there any harm in using starter fluid on my Craftsman riding lawnmower?
Using starter fluid occasionally in cold weather is generally safe. However, excessive use or improper application can cause damage to your Craftsman riding lawnmower’s engine.
Over time, frequent use of starter fluid can erode internal engine parts and contribute to engine wear. Additionally, it can cause the engine to run too rich, leading to problems with fuel efficiency and emissions.
7. What should I do if my Craftsman riding lawnmower still won’t start after using starter fluid?
If your Craftsman riding lawnmower still won’t start after using starter fluid, it’s best to seek professional help. There may be a more serious underlying issue that requires the expertise of a mechanic.
Possible causes include a faulty fuel system, spark plugs, or ignition system. A qualified mechanic can diagnose the problem and make the necessary repairs to get your lawnmower running smoothly again.
