A Quick Overview
Several factors can prevent your Craftsman mower from starting. The most common culprits include:
- Fuel-related issues: A lack of fuel, old fuel, or a clogged fuel line can all hinder your mower’s ability to start.
- Ignition problems: A faulty spark plug, a broken ignition switch, or a dead battery can all interrupt the spark needed to ignite the fuel.
- Engine-related issues: A flooded engine, a clogged air filter, or even a simple lack of oil can create starting issues.
Let’s break down each of these common problems and learn how to solve them.
Fuel-Related Issues
The first step in troubleshooting a non-starting mower is checking the fuel system.
Is the Fuel Tank Empty?
This may seem obvious, but a surprisingly large number of lawn mower troubles stem from a simple lack of fuel. Before you dive into more complex issues, ensure the fuel tank has some gas.
Is the Fuel Old?
Gasoline degrades over time, especially if it’s been sitting in the tank for a while. Old fuel can gum up the fuel lines and carburetor, making it difficult for the engine to start.
- Solution: If you suspect the fuel is old, drain it and refill the tank with fresh, high-octane gasoline. You can also add a fuel stabilizer to help prevent future degradation.
Is the Fuel Line Clogged?
A clogged fuel line can prevent fuel from reaching the carburetor, preventing the engine from starting.
- Solution: Inspect the fuel line for any kinks or obstructions. You can also try blowing through the line with compressed air to clear any blockages.
Is the Fuel Filter Clogged?
A clogged fuel filter can restrict the flow of fuel to the engine.
- Solution: You can usually find the fuel filter near the fuel tank or along the fuel line. If it appears dirty or clogged, replace it with a new one.
Ignition System Problems
If the fuel system checks out, the next culprit to investigate is the ignition system.
Is the Spark Plug Faulty?
A faulty spark plug can prevent a spark from igniting the fuel mixture, making the engine unable to start.
- Solution: Use a spark plug wrench to remove the spark plug. Inspect it for damage, cracks, or excessive wear. If it’s in poor condition, replace it with a new one.
Is the Ignition Switch Defective?
The ignition switch controls the flow of electricity to the engine, so a faulty switch can stop the engine from starting.
- Solution: If the ignition switch is broken or not working properly, you’ll need to replace it.
Is the Battery Dead?
A dead battery can prevent the ignition system from working, rendering your mower useless.
- Solution: If the battery terminals are corroded, clean them with a wire brush. If the battery is completely dead, you’ll need to replace it with a new one.
Engine Problems
While fuel and ignition issues are the most common culprits, there are also engine-related problems that can prevent your Craftsman mower from starting.
Is the Engine Flooded?
A flooded engine occurs when too much fuel enters the combustion chamber, preventing the engine from starting. This can happen if you try to start the engine repeatedly without success.
- Solution: If you think your engine is flooded, let it sit for a few minutes to allow the excess fuel to evaporate. Then, try starting the engine again. You can also try turning the ignition key to the “start” position for a few seconds without engaging the starter motor to clear out excess fuel.
Is the Air Filter Clogged?
A clogged air filter restricts the flow of air to the engine, making it difficult to start.
- Solution: Inspect the air filter for dirt and debris. If it’s dirty, replace it with a new one.
Is the Engine Out of Oil?
Low oil levels can damage the engine and prevent it from starting.
- Solution: Check the oil level using the dipstick. If it’s low, add more oil until it reaches the full mark.
Other Potential Issues
In addition to the problems mentioned above, there are a few other potential reasons why your Craftsman mower might not start:
- Choke is engaged: Some mowers have a choke lever that needs to be disengaged after the engine has warmed up.
- Safety interlock switch: Many modern lawn mowers have safety interlock switches that prevent the engine from starting if the blades are not engaged. Check to make sure the blades are in the correct position.
Getting Help
If you’ve checked all of the above and your Craftsman mower still won’t start, it’s time to seek professional help. A local lawn mower repair shop can diagnose the problem and fix it for you.
Preventative Maintenance
To keep your Craftsman mower running smoothly and prevent starting problems, it’s important to practice regular preventative maintenance.
- Change the oil regularly: Consult your owner’s manual for recommended oil change intervals.
- Clean the air filter: A dirty air filter restricts airflow to the engine, affecting performance and fuel economy.
- Check the spark plug: Inspect the spark plug for wear and tear and replace it as needed.
- Store the mower properly: During the off-season, store your mower in a dry, clean place with a full fuel tank and a stabilized fuel mixture.
