What is the general lifespan of a carburetor?

[Malia]

The lifespan of a carburetor is generally around 3 to 5 years. The reasons for carburetor leakage include: 1. Foreign objects stuck in the main fuel needle causing the fuel level to continuously rise and leak; 2. Wear and tear of the needle valve leading to improper sealing; 3. The float getting stuck and failing to close the needle valve. The function of a carburetor is to mix a certain amount of gasoline with air to ensure the engine operates normally. Symptoms of a damaged carburetor include: 1. Unstable engine idling; 2. Difficulty or inability to start the vehicle, with the spark plug failing to ignite properly; 3. Black smoke from the exhaust pipe during rapid acceleration, affecting exhaust emissions. Methods to address a damaged carburetor include: 1. Replacing with qualified float needles and needle seat components; 2. Using a float needle seat repair tool for restoration; 3. After processing, the top must be polished with flannel cloth.
