How to clean a carburetor on a moped?


Cleaning the carburetor on a moped is an essential maintenance task that can greatly improve its performance and fuel efficiency. 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 guide you through the process of cleaning a carburetor on a moped, ensuring that your vehicle runs smoothly and efficiently.

Gather the necessary tools and materials

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

Materials used:
– Carburetor cleaner
– Compressed air
– Clean rags or towels
– Safety goggles
– Gloves

Tools needed:
– Screwdriver
– Wrench
– Needle-nose pliers
– Small brush or toothbrush

Prepare the moped

Start by turning off the engine and allowing it to cool down. It is also recommended to disconnect the battery to prevent any accidental starting. Next, locate the carburetor on your moped. It is typically situated near the engine and is connected to the air filter and fuel line.

Remove the carburetor

To clean the carburetor effectively, it is best to remove it from the moped. Begin by disconnecting the fuel line and any other connections attached to the carburetor. Take note of the connections and their positions to ensure proper reassembly later. Use a wrench or screwdriver to remove the mounting bolts or clamps holding the carburetor in place. Carefully detach the carburetor from the engine.

Disassemble the carburetor

Once the carburetor is removed, carefully disassemble it. Start by removing the float bowl, which is usually held in place by screws or bolts. Take note of the orientation of the float and the needle valve for reassembly. Inspect the float bowl for any sediment or debris and clean it thoroughly with carburetor cleaner.

Next, remove the main jet and idle jet using a screwdriver or wrench. These jets can become clogged with deposits and should be cleaned using compressed air. Ensure that all passages and orifices are clear of any obstructions.

Clean the carburetor components

Using carburetor cleaner, thoroughly clean all the components of the carburetor. Pay close attention to the jets, float, and needle valve. Use a small brush or toothbrush to remove any stubborn deposits. Ensure that all the passages and orifices are completely clean and free from any blockages.

Reassemble and reinstall the carburetor

Once all the components are clean and dry, reassemble the carburetor in the reverse order of disassembly. Make sure to properly align the float and needle valve. Tighten all screws and bolts securely but avoid overtightening.

After reassembling the carburetor, carefully reinstall it onto the moped’s engine. Reconnect the fuel line and any other connections that were detached earlier. Double-check all the connections to ensure they are secure.


Cleaning the carburetor on your moped is a relatively simple process that can greatly improve its performance and fuel efficiency. By following the steps outlined in this article, you can effectively clean your moped’s carburetor and ensure that it runs smoothly and efficiently.
