How to Clean a Carburetor?

Remove the air cleaner, start the engine, and bring it to a higher RPM. Quickly cover the carburetor intake with your palm. You should feel a strong suction, and the engine RPM will gradually decrease. When the engine RPM is sufficiently low, quickly remove your palm to allow the engine to return to normal operation.
Cleaning the carburetor, I share my experience as a long-term DIY car owner. The first step is ensuring safety: turn off the engine first and disconnect the negative battery terminal to avoid short circuits. Then remove the carburetor body, wear gloves, and spray the interior with a specialized cleaner, focusing on cleaning the nozzle holes and small passages where dirt buildup can easily cause fuel blockage and unstable idling. Use a soft brush or compressed air to gently remove residues, and check if the gaskets and springs are worn out. After cleaning, carefully reassemble, aligning the screw positions without overtightening. Perform the entire process in a well-ventilated area, taking about an hour. After completion, the engine will start more smoothly, and fuel consumption will improve. I clean it regularly every six months to prevent major issues and save on repair costs.
As a beginner in car repair, cleaning the carburetor requires a step-by-step approach. After disconnecting the battery, remove the carburetor and place it on the workbench. Spray carburetor cleaner into the air intake and let it soak for 10 minutes to dissolve carbon deposits. Then, use a fine brush to gently clean the holes and wipe off external oil stains. When reinstalling, align the bolt holes properly—beginners often misalign them, causing air leaks or blockages that lead to ignition issues. It's advisable to watch online tutorials or practice on simpler car models first. Having a friend assist is safer, as lacking the right tools can easily damage parts. The entire process requires patience to avoid sudden failures.
When cleaning the carburetor, I emphasize efficient methods. Ensure the engine is cold, disconnect the battery, and after disassembly, thoroughly spray cleaner into all internal passages. Focus on cleaning the jets and float chamber to prevent blockages that could affect the air-fuel mixture ratio. Inspect parts for damage and replace them promptly, such as worn gaskets that may cause fuel leaks. During reassembly, ensure proper alignment and avoid using excessive force when tightening screws. Regular cleaning can prevent issues like engine failure to start or sluggish acceleration, extending component lifespan.
