Unhook the throttle cable from the carburetor, along with any other associated connections. DIY Tip: Make reassembly easier by taking photos of the carburetor before removing and disassem- bling it. Take photos from several angles to provide a visual refer- ence to help guide reinstallation of the various parts.
To clean the outside of the car- buretor, an old toothbrush makes a good tool for scrubbing off dirt and surface grime. Next, use a screwdriver or wrench to remove any screws or bolts that hold the bowl onto the carburtor. A carburetor will have several small parts, so you should collect them all in a bowl or pan. Although carburetors vary some- what in design, they usually consist of a bowl, float, needle, seat, rub- ber O-rings, etc. Pay attention to the fitment of these parts when dissecting the carburetor. Note: You might be able to find a carbu- retor rebuild kit that matches your model, and the kits will have replacement rings and gaskets. Once the carburetor is complete- ly disassembled, thoroughly spray all the holes or openings with
Small Engine Carb Cleaner, which should be available at your local hardware store. The carburetor needs to blend air and gas in pre- cise amounts, and any small amount of blockage can impede its performance. In addition to using the chemical cleaner, I recommend also thread- ing a thin-gauge wire through all the little holes and passages of the carburetor. For the wire, a common bread tie works well (after using a lighter to burn off its paper wrap- ping). After the wire, spray all parts again with the cleaner to force out any grime or debris you've dis- lodged. Allow the cleaner to remain on the carburetor so it has time to dissolve any residual blockage. Do the same for the smaller compo- nents. Soaking the parts for an hour is not unreasonable, and I recommend respraying all surfaces several times for good measure. To remove the fuel line, use pliers to slide back the clip, pull the tube's end off the carburetor nip- ple, and clamp it so fuel doesn't leak out.
Slide the carburetor off its mount- ing pins, then scrub off all exterior dirt and grime
Disassemble the carburetor in a pan. First, remove the screw that holds on the bowl, then take out the interior parts, taking photos as you work.
Use a can of Small Engine Carb Cleaner to wash all the parts. A thin-gauge wire (such as a bread tie) can be used to auger out the holes and passages of the carburetor.
Spray the cleaner into every opening. Soak the components thoroughly.
Use the wire in every opening and passage to force out any unseen blockage.
The carburetor will have lots of holes and openings to mix the air and fuel.
