What Causes Carburetor Oil Leakage?
2 Answers
The reasons for carburetor oil leakage are: 1. The main fuel needle is stuck by foreign objects, causing the fuel level to continuously rise and leak; 2. The needle valve is worn and does not close tightly, leading to leakage; 3. The float is stuck and cannot close the needle valve. The solutions for carburetor oil leakage are: 1. Disassemble the carburetor, clean the float chamber, main fuel needle, and its valve; 2. Replace the needle valve and adjust both ends of the float to be at the same level; 3. Regularly clean the gasoline filter; 4. Use high-quality gasoline; 5. Replace the float. The working principle of a carburetor is to mix a certain amount of gasoline with air to ensure the engine operates normally.
Oh, I had the same issue with my old car before. Carburetor oil leakage is really annoying. The most common cause might be worn or aged gaskets – over time, oil slowly seeps out. If there's a problem with the float chamber, like small parts getting stuck or improper adjustment causing the fuel level to be too high, it can also overflow. Another possibility is the needle valve not sealing tightly, allowing oil to continuously leak. Temperature changes and frequent starts can worsen the problem. I must remind you that oil leakage not only affects fuel consumption but may also cause oil accumulation under the hood, posing a fire hazard. When I discovered it back then, I first wiped it dry with paper towels to check the leak source, then went to the repair shop to replace the gasket – fixed it right away. Regularly inspecting these components when driving an old car is really important; don't wait until oil starts leaking to take action.
