2. Faulty fuel pump: The fuel pump is responsible for delivering fuel from the gas tank to the carburetor. If the fuel pump is faulty, it can fail to deliver enough fuel to the carburetor.
3. Vacuum leak: A vacuum leak can cause the fuel mixture to become too lean, which can prevent the engine from starting or running properly.
4. Faulty fuel pressure regulator: The fuel pressure regulator controls the amount of fuel pressure delivered to the carburetor. If the fuel pressure regulator is faulty, it can cause the fuel pressure to be too high or too low, which can affect the engine's performance.
5. Faulty carburetor: The carburetor mixes air and fuel together to create a combustible mixture for the engine. If the carburetor is faulty, it can fail to mix the air and fuel properly, which can prevent the engine from starting or running properly.
