Cleaning the carburetor on a leaf blower is an essential maintenance task that can help improve its performance and extend its lifespan. Over time, carburetors can become clogged with dirt, debris, and old fuel, leading to poor engine performance and starting issues. In this article, we will delve into the step-by-step process of cleaning a carburetor on a leaf blower, ensuring that your equipment runs smoothly and efficiently.

Gather the necessary tools and materials

Before starting the carburetor cleaning process, it is important to gather all the necessary tools and materials. Here are the items you will need:

– Carburetor cleaner
– Fresh gasoline
– Clean rags or paper towels
– Safety goggles
– Latex gloves

– Screwdriver (flathead or Phillips, depending on the carburetor screws)
– Small brush (such as a toothbrush)
– Compressed air can or air compressor (optional, but recommended)

Prepare the leaf blower

To ensure safety and ease of access, it is best to start by preparing the leaf blower for carburetor cleaning. Here’s what you need to do:

1. Turn off the leaf blower: Make sure the engine is completely turned off and cool before proceeding with any maintenance tasks.

2. Remove the spark plug wire: Disconnect the spark plug wire from the spark plug to prevent accidental starting during the cleaning process.

Access the carburetor

Once the leaf blower is prepared, you can proceed to access the carburetor for cleaning. The steps may vary slightly depending on the leaf blower model, but the general process is as follows:

1. Locate the carburetor: The carburetor is typically located near the air filter, behind a cover or housing. Consult your leaf blower’s manual if you are unsure about its exact location.

2. Remove the carburetor cover: Use a screwdriver to remove the screws securing the carburetor cover. Carefully lift off the cover, exposing the carburetor.

Clean the carburetor

Now that you have accessed the carburetor, it’s time to clean it thoroughly. Follow these steps:

1. Spray carburetor cleaner: Use a carburetor cleaner specifically designed for small engines. Spray the cleaner onto the various components of the carburetor, including the throttle plate, choke plate, and jets. Pay extra attention to any visible dirt or debris.

2. Scrub with a brush: Use a small brush, such as a toothbrush, to gently scrub the components of the carburetor. This will help remove any stubborn grime or residue.

3. Blow out with compressed air: If available, use compressed air to blow out any remaining cleaner and debris from the carburetor. This step helps ensure a thorough cleaning.

4. Reassemble the carburetor: Once the carburetor is clean and dry, carefully reassemble all the components in the reverse order of disassembly. Make sure all screws are tightened securely.


Cleaning the carburetor on a leaf blower is a relatively simple process that can greatly improve its performance. By following the step-by-step instructions outlined in this article, you can effectively remove dirt, debris, and old fuel from the carburetor, ensuring optimal engine performance and longevity.

Remember, regular maintenance and cleaning of the carburetor, along with other essential parts of the leaf blower, will help keep it running smoothly for years to come.
