Safety Precautions
Cleaning the carburetor on your Husqvarna lawn mower requires attention to safety. Follow these precautions to ensure a safe cleaning experience:
- Turn Off the Engine: Before starting any maintenance, shut off the mower’s engine. Allow it to cool down completely to prevent burns.
- Disconnect the Spark Plug: Remove the spark plug wire to prevent accidental starting. This step adds an extra layer of safety during your cleaning process.
- Use Protective Gear: Wear gloves, goggles, and a mask. These items protect your hands from chemicals, your eyes from debris, and your lungs from fumes.
- Work Outdoors or in a Well-Ventilated Area: Ensure adequate ventilation to disperse harmful vapors from cleaning solvents. Working outside minimizes the risk of inhaling toxic fumes.
- Handling Fuel Carefully: When removing the fuel line, handle fuel cautiously to prevent spills. Use a container specifically designed for fuel storage.

- Follow Equipment Instructions: Adhere to the manufacturer’s instructions for the carburetor cleaning process. Proper guidance ensures safer and more effective cleaning.
By following these safety precautions, you can clean your carburetor effectively while minimizing risks.
Step-by-Step Cleaning Process
Cleaning the carburetor on your Husqvarna lawn mower can boost its performance. Follow these steps to ensure a thorough cleaning.
Remove the Carburetor
- Turn off the engine and disconnect the spark plug to ensure safety.
- Locate the carburetor, usually mounted on the engine.
- Use a screwdriver to detach any bolts or clips securing the carburetor.
- Gently pull the carburetor away from the engine, being cautious with attached fuel lines.
Disassemble the Carburetor
- Place the carburetor on a clean, flat surface.
- Remove the screws holding the top cover in place using a screwdriver.
- Take off the float bowl by unscrewing the bolt at the bottom.
- Carefully remove the float and needle, paying attention to their positions.
Clean the Components
- Use a cleaner spray to wash all removable parts, including the float bowl and cover.
- Clean the jets and passages using a small brush or compressed air.
- Inspect for any gunk or residue; if present, soak the parts in cleaner for deeper cleaning.
- Rinse the components thoroughly with clean water, ensuring no cleaner residue remains.
- Reattach the float and needle in their original positions.
- Secure the float bowl back onto the carburetor, tightening the bolt.
- Place the top cover back in place and fasten it with screws.
- Reinstall the carburetor onto the engine, connecting any fuel lines properly.
Tips for Maintenance
- Regular Cleaning: Clean the carburetor every season or after every 25 hours of use. This prevents buildup that causes starting issues.
- Inspect Fuel: Use fresh fuel in your lawn mower. Old or contaminated fuel can clog the carburetor. Replace fuel every month if you don’t use the mower often.
- Check Gaskets: Look for cracks or wear in the carburetor gaskets. Replacing worn gaskets maintains a proper seal and fuel flow.
- Store Properly: Store the lawn mower in a dry and cool area. Avoid letting moisture accumulate, which can lead to rust and corrosion.
- Use Additives: Consider using fuel stabilizers. These additives help keep fuel fresh longer and prevent varnish buildup in the carburetor.
- Test Regularly: Run the mower regularly to keep parts moving smoothly. This practice helps prevent fuel from gumming up.
- Replace Filters: Check the air and fuel filters every season. Clogged filters restrict fuel flow and air intake, leading to performance issues.
- Listen for Issues: Pay attention to sounds while mowing. Unusual noises can indicate problems with the carburetor or other engine parts.
- Consult the Manual: Refer to your Husqvarna lawn mower manual for specific maintenance recommendations. Following manufacturer guidelines ensures the best performance.
- Seek Professional Help: If issues persist despite your efforts, consider consulting a professional. They can diagnose deeper problems that may affect performance.
