Remove the air cleaner assembly. Then either remove the fuel from the fuel tank or use a fuel line clamp to stop the flow of fuel and unhook the fuel line. Remove the carburetor. Then remove the bolt that secures the bowl and clean the bowl. Remove the float by removing the float pin.Then remove the parts on the carburetor. Use carburetor cleaner to clean the carburetor inside and out. Use fishing line to clear out the small passages, using anything metal can damage those passages. Now you can start the rebuild by using the parts in the kit. Install all the parts in reverse order. And you're done
