1. Clogged Carburetor:
- Check if the carburetor is clogged. Dirt and debris can accumulate in the carburetor, blocking fuel flow and causing the engine to run lean. Clean the carburetor thoroughly, including the jets, float bowl, and air filter.
2. Incorrect Fuel Mixture:
- Make sure the fuel mixture is correct. Briggs & Stratton engines typically require a ratio of 50:1 (gasoline to oil). If the mixture is too lean (too much gasoline), the engine may run rough or not at all.
3. Faulty Spark Plug:
- Check the spark plug. If the spark plug is worn or damaged, it can cause ignition problems and prevent the engine from running properly. Replace the spark plug with a compatible one.
4. Blocked Air Filter:
- Check if the air filter is blocked. A clogged air filter can restrict airflow and cause the engine to run rich (too much fuel). Clean or replace the air filter.
5. Float Adjustment:
- Check the float level in the carburetor. If the float is not adjusted correctly, it may cause the engine to run rich or lean. Ensure the float moves freely and is properly adjusted.
6. Fuel Line Issue:
- Check the fuel line for any kinks or restrictions. Ensure that the fuel line is clear and not cracked. Replace it if necessary.
7. Choke Mechanism:
- Inspect the choke mechanism for proper operation. Make sure the choke lever is moving smoothly and the choke plate is closing fully when engaged.
If the problem persists, it's recommended to consult with a small engine repair professional for further diagnostics and assistance. They will be able to accurately troubleshoot the issue and perform necessary repairs.
