1. Fuel:
- Ensure that you added gasoline to the mower's fuel tank.
- Make sure you used the correct type of fuel for your mower (usually unleaded gasoline).
- Check the gas tank for any blockages or debris that may prevent fuel from flowing.
2. Fuel System:
- Check the fuel filter and replace it if it's dirty or clogged.
- Verify if there are any kinks or blockages in the fuel line.
- Verify that the fuel line is properly connected to both the fuel tank and carburetor.
3. Spark Plug:
- Inspect the spark plug and replace it if necessary.
- Ensure the spark plug is properly seated and connected to the spark plug wire.
4. Ignition System:
- Examine the ignition switch and ensure it's in the "ON" position.
- Check the ignition coil and wiring to make sure there aren't any loose or damaged components.
5. Battery:
- Verify that the battery terminals are clean and free of corrosion.
- Ensure the battery is properly secured and has sufficient charge. If it's a rechargeable battery, try charging it.
6. Choke:
- Make sure the choke is in the correct position. Typically, the choke should be engaged (pulled out) when starting a cold engine and disengaged (pushed in) once it starts.
7. Engine Oil:
- Check the engine oil level and add more if necessary. Insufficient oil can cause engine issues, including starting problems.
If you've checked these items and the mower still won't start, there might be a more complex issue at hand, such as a faulty starter solenoid, carburetor problems, or a worn-out starter motor. In such cases, it's best to consult a small engine repair professional for assistance.
