1. Check the throttle stop lever. Make sure that the throttle stop lever is in the "Run" position. If it is not, the engine will not be able to get enough fuel to run properly.
2. Check the carburetor. Make sure that the carburetor is clean and properly adjusted. A dirty or misadjusted carburetor can cause the engine to stall.
3. Check the fuel filter. Make sure that the fuel filter is clean and not clogged. A clogged fuel filter can restrict fuel flow to the carburetor and cause the engine to stall.
4. Check the air filter. Make sure that the air filter is clean and not clogged. A clogged air filter can restrict air flow to the carburetor and cause the engine to stall.
5. Check the spark plug. Make sure that the spark plug is properly gapped and that the connections are secure. A faulty spark plug can cause the engine to stall.
