Turn off the fuel supply and disconnect the fuel line. Use an 8mm or 10mm wrench to remove the nuts connecting the carburetor to the engine. Use a Phillips screwdriver to remove the three screws on the carburetor float chamber cover. Spray carburetor cleaner into each jet (be careful not to aim your eyes at the carburetor to avoid getting cleaner in your eyes). After cleaning, reassemble the carburetor.
When cleaning the carburetor of a pedal motorcycle, I found that as an ordinary user, it's crucial to prepare necessary tools beforehand, such as a small wrench, specialized carburetor cleaner, a soft-bristled brush, and protective gloves. Ensure the motorcycle is in a cool state before operation, disconnect the negative battery terminal before disassembly, and then carefully remove the carburetor cover and connecting pipes. During the cleaning process, I prefer to disassemble the carburetor block by block, spraying each component with cleaner, focusing on cleaning the nozzle holes and float chamber, avoiding the use of metal tools to prevent surface scratches. After cleaning, let it dry for at least an hour before reassembling. Regular cleaning every six months can prevent fuel line blockages that cause starting difficulties. I recommend beginners start with simpler models and consult tutorial videos to avoid mistakes.
As a long-time riding enthusiast, there are several key techniques to master when cleaning a carburetor: First, mark the positions of hoses and screws during disassembly for easy reassembly. Then, use a small brush and compressed air to clean the nozzle holes, ensuring no residual oil remains. I've noticed many people overlook float adjustment—check its height after cleaning to prevent fuel leaks. Opt for eco-friendly cleaners for safety, and avoid working in enclosed spaces to prevent inhaling fumes. The cleaning process takes about two hours. After completion, start the engine to test if the idle is smooth; if it shakes, components might be installed backward. Regular maintenance improves fuel efficiency and reduces emissions. I've also observed significant differences in cleaning frequency among various brand scooters.
