To clean the carburetor on a Kawasaki FE120G, you’ll need some basic tools, carburetor cleaner, and a bit of patience. Here’s a step-by-step guide:
Tools and Materials:
- Screwdrivers (Phillips and flathead)
- Wrenches
- Carburetor cleaner spray
- Compressed air (optional)
- Gloves and safety goggles

Steps:
- Turn Off and Cool Down: Make sure the engine is off and cooled down before you start working on it.
- Remove the Air Filter Housing:
- Start by removing the air filter cover and the air filter itself.
- Unscrew the housing of the air filter to expose the carburetor.
- Disconnect Fuel Line:
- Use a clamp or pinch-off tool to block fuel flow.
- Disconnect the fuel line from the carburetor, and be ready to catch any fuel that spills out.
- Remove the Carburetor:
- Unscrew and remove the bolts that hold the carburetor to the engine.
- Gently disconnect the throttle and choke linkages attached to the carburetor. Take note of where each linkage is connected for reassembly.
- Disassemble the Carburetor:
- Once removed, carefully take apart the carburetor, removing the float bowl (usually held on by screws).
- Inspect the float, needle valve, and jets. Handle these small parts with care.
- Clean the Carburetor:
- Spray carburetor cleaner into the jets, ports, and all small passageways to break down dirt, varnish, and gunk.
- If any jets are clogged, use a small wire or a jet cleaning tool to clear them out.
- Use compressed air to blow out any remaining debris.
- Inspect the Carburetor:
- Check the gaskets, seals, and O-rings for wear. Replace them if necessary.
- Reassemble the Carburetor:
- Once everything is cleaned and dry, reassemble the carburetor by putting the jets, float, and bowl back in place.
- Make sure everything is tightened securely but not over-tightened.
- Reinstall the Carburetor:
- Reattach the throttle and choke linkages.
- Bolt the carburetor back onto the engine.
- Reconnect the fuel line and ensure it’s secure.
- Reinstall the Air Filter Housing:
- Put the air filter housing and air filter back on.
- Test the Engine:
- Turn on the fuel supply, and try to start the engine.
- Adjust the carburetor settings (like idle speed and air-fuel mixture) as needed once the engine is running smoothly.
Tips:
- If you are unsure about disassembling the carburetor, take pictures as you go to help with reassembly.
- Wear gloves and safety goggles when handling carburetor cleaner, as it can be harmful if it contacts skin or eyes.
