Cleaning motorcycle carburetor

Carburetors should be cleaned in a clean place. Clean the outer surface of the carburetor first, and the inside can be cleaned with special cleaning agent for carburetor or industrial gasoline. In addition to impurities, attention should also be paid to cleaning the gasoline glue on the surface of parts. Blow the cleaned parts clean with compressed air, and do not wipe them with cloth or paper that will produce burrs to prevent re-pollution. It is forbidden to poke the blocked small hole with hard objects such as steel wire to prevent the carburetor performance from changing due to changing the aperture. It should be cleaned with gasoline or compressed air.

0 1 Remove the motorcycle carburetor.

Unplug the oil pipe and gas pipe, remove the throttle cover and pull out the throttle. Remove the wire rope on the throttle, loosen the fixing screws at both ends of the carburetor, and remove the carburetor.

Remove the three screws of the float chamber.

Next, start cleaning the carburetor.

Wipe the surface of the oiler with gasoline. Open the float chamber and take out the float and the float oil needle. If there is sediment at the bottom of the float chamber, find something to scrape it off gently, and then rinse it with gasoline.

Remove the air conditioning screw, main metering hole and idle metering hole. Clean all parts with gasoline. Some parts that are not easy to clean, such as oil stains, can be soaked in industrial alcohol and then brushed with a brush. When cleaning, the oil slick needle and needle holder, main metering hole and nozzle, idle metering hole and idle nozzle should be taken as the cleaning focus.

If the hole in the carburetor is blocked, you can pump it a few times or poke it with a wire or needle thinner than the hole. You can't poke with something larger than the diameter of the hole.

After cleaning, assemble it in the reverse order, and finally make the final adjustment to the carburetor. And check whether there are any problems, such as whether the float leaks and whether the float needle valve is closed tightly.
