6.5 Briggs and Stratton stops when mowing on a slope?

1. Check the fuel level. If the fuel level is low, the engine may not be getting enough gas to run properly. Fill up the gas tank and try mowing again.

2. Clean the air filter. A dirty air filter can restrict airflow to the engine, causing it to stall. Remove the air filter and clean it with soap and water. Let the air filter dry completely before reinstalling it.

3. Check the spark plug. A worn or damaged spark plug can cause the engine to stall. Remove the spark plug and check the condition of the electrode. If the electrode is worn or damaged, replace the spark plug.

4. Check the fuel line. A kinked or damaged fuel line can restrict fuel flow to the engine, causing it to stall. Check the fuel line for any kinks or damage. If the fuel line is kinked or damaged, replace it.

5. Check the carburetor. A dirty or clogged carburetor can cause the engine to stall. Remove the carburetor and clean it with carburetor cleaner. Make sure to clean all of the jets and passages in the carburetor.

6. Check the governor. A faulty governor can cause the engine to stall. Check the governor for any damage or wear. If the governor is damaged or worn, replace it.
