If the fuel line is leaking, the engine will not receive enough fuel to keep running. Check the line for any cracks or holes and replace it if necessary.
Inspect the carburetor for dirt or debris.
The carburetor is responsible for mixing fuel and air to create a combustible mixture. If the carburetor is dirty or clogged, it will not be able to mix fuel and air properly, which will cause the engine to stall. Clean the carburetor with carb cleaner and a brush if necessary.
Check the spark plug for wear or damage.
The spark plug is responsible for igniting the fuel in the cylinder. If the spark plug is worn or damaged, it will not be able to create a spark, which will cause the engine to stall. Replace the spark plug if necessary.
Check the battery for a good charge.
If the battery is not properly charged, it will not be able to provide enough power to start the engine or keep it running. Charge the battery if necessary.
Check the air filter for dirt or debris.
The air filter is responsible for filtering dust and dirt out of the air before it enters the carburetor. If the air filter is dirty or clogged, it will not be able to filter out dust and dirt, which can damage the engine. Clean the air filter with compressed air or a brush if necessary.
Check the oil level.
If the oil level is too low, the engine will not be properly lubricated, which can cause it to stall. Add oil to the engine if necessary.
Check the coolant level.
If the coolant level is too low, the engine will not be properly cooled, which can cause it to overheat and stall. Add coolant to the engine if necessary.
If you have checked all of these things and the engine still stalls, you should take it to a mechanic for further diagnosis.
