Prepare the Generator

To begin the cleaning process, it is important to prepare the generator properly. Follow these steps:

1. Turn off the generator: Make sure the generator is completely turned off and disconnected from any power sources.

2. Locate the carburetor: The carburetor is typically situated near the engine and is connected to the air filter and fuel line.

3. Remove the air filter: Depending on your generator model, you may need to remove the air filter to access the carburetor. Refer to your generator’s manual for specific instructions.

Cleaning the Carburetor

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

1. Remove the carburetor cover: Use a screwdriver or wrench to remove the screws or bolts securing the carburetor cover. Carefully lift off the cover to expose the carburetor.

2. Spray carburetor cleaner: Using the carburetor cleaner, spray all the visible components of the carburetor, including the throttle plate, choke plate, and jets. Pay close attention to any clogged or dirty areas.

3. Let the cleaner soak: Allow the carburetor cleaner to penetrate and dissolve the dirt and varnish for a few minutes. This will help loosen any stubborn deposits.

4. Clean with compressed air: After the cleaner has had time to work, use compressed air to blow away the loosened debris. Be thorough in cleaning all the nooks and crannies of the carburetor.

5. Wipe clean: Use clean rags or paper towels to wipe away any remaining cleaner and debris. Ensure that all surfaces are clean and free from residue.

Reassembling the Carburetor

Once the carburetor is clean, it’s time to reassemble it. Follow these steps:

1. Replace the carburetor cover: Carefully place the carburetor cover back in its original position and secure it with the screws or bolts.

2. Reinstall the air filter: If you removed the air filter earlier, make sure to reinstall it properly.

3. Connect the fuel line: Reconnect the fuel line to the carburetor, ensuring a secure connection.

4. Test the generator: Start the generator and observe its performance. If the cleaning process was successful, you should notice improved engine performance and smoother operation.


Cleaning the carburetor of your generator is a crucial maintenance task that can significantly impact its performance and longevity. By following the step-by-step process outlined in this article, you can effectively clean the carburetor and ensure optimal generator operation.
