Cleaning a car carburetor is not as difficult as you think. It may sound complicated, but you don’t have to be a carburetor expert.
Keeping the carburetor clean is not an easy task. Especially when it properly adjusts the fuel-air mixture to provide the internal combustion that takes place inside the engine and keep the engine running. But cleaning the carburetor is as easy as 1, 2, 3 by following our preferred method.
This post will walk you through the step-by-step process of how to clean your car’s carburetor and the tools you’ll need to do it.
- Carburetor cleaner (can be purchased online or at a local hardware store)
- 10mm combination wrench or socket (an adjustable wrench can be used if your carb has a different nut size)
- Smaller-sized flat head screwdriver
- Needle-nose pliers
- Thin-gauge wire or needle
Make sure the engine and muffler are cool before starting any maintenance. Follow all safety instructions in your owner’s manual. Please use common sense. Clean the carburetor in a well-ventilated place, because the carburetor emits gasoline fumes.
How To Clean a Carburetor – Step by Step Guide
Check your owner’s manual before cleaning the carburetor. Always follow the manufacturer’s complete instructions for cleaning and maintenance. Make sure the carburetor is cool before cleaning.
- Diluted cleaner: Mix the diluted cleaner in a large bowl. However, it is important to use a non-corrosive cleaner that will not damage or destroy the plastic parts of the carburetor or tires. Avoid using vinegar because the acetic acid makes the metal susceptible to rust. Also, never use bleach, as sodium hypochlorite (bleach) will corrode metals such as steel and aluminum and destroy rubber seals.
- Clean the air filter: Before cleaning the carburetor, check the air filter to make sure that the air entering the carburetor is clean and free of blockages that cause black smoke from the exhaust. Turn off the fuel source and disconnect the spark plug wires if present. Remove the wing nut that connects the housing to the filter and remove the outer element. Use a can of compressed air to remove debris.
- Remove the carburetor. Use pliers and a screwdriver to remove the cover plate or shield, fittings and hoses as needed. Also remove the cover or clip that holds the carb in place and remove the hose clamp that connects it to the fuel line. Remove the carburetor and use compressed air to remove excess dirt from the outer casing. (Note: If you are not familiar with this method, consult a professional before cleaning.)
- Remove other removable components: Note the location and placement of any other carburetors components you’re removing to allow cleaning access.
- Removing the carburetor float: Remove the bolt that secures the carburetor float (bowl housing) and be careful not to spill any gas left in the float (dispose of it properly). This is a common point of varnish accumulation on the carburetor. Also remove the pin that the float rotates on and put it in a safe place. Pull the float straight out of the housing.
- Remove other removable components: Pay attention to the location of other carburetor components you are removing to allow for cleaning access.
- Soaking and scrubbing components: Submerge the carburetor float and other components in a large container of diluted cleaner and allow to soak thoroughly for 10 minutes. Use a brass brush to clean all metal parts and a stiff nylon brush to clean plastic parts. Make sure the small vents are cleaned. Clean small parts with cleaning solution.
- Washing and drying: Wash all carburetor components with a bucket of clean water and allow to air dry completely. For small holes or vents, use a can of compressed air to remove excess moisture.
- Reassembly and replacement: Carefully assemble the carburetor and install it on the engine. Reconnect all hoses, clamps and wires.

How To Clean A Carburetor Without Removing It?
To clean a motorcycle carburetor without removing it, you’ll need to remove the bowls at the bottom of the carburetor. Once the bowls are removed, spray some carburetor cleaner up inside, wait a few minutes, then spray again to ensure coverage. Then replace the bowls and start the motorcycle to assess how it runs.
Here’s the process:
- Safety checks. Have you turned off the petrol? Do you use mechanic gloves (carb and gasoline cleaners are bad for your skin)? Is your bike cold (hot exhaust pipes are bad for gas exhaust) Every shed should also have a fire extinguisher?
- Move your bike to a clean floor. Carbs are full of small parts – god forbid you drop them, but if you do, a clean floor means you might find them.
- Place a simple cloth on the body under the carburetor. This cleaner absorbs fuel and carbs cleaner and helps if small parts are left behind.
- Drain the float bowl. There should be only one bolt or screws at the base of the carburetor. Turn it back on slowly and the fuel starts to leak. If possible, take it in a pan. If the fuel supply continues, it might be better to turn off the petrol…
- Remove the float bowl, which is often held in place by four cross-head screws. Check the floating bowl for gunge. If you have loads, you are on the right track. Clean with carb cleaner spray.
- Remove the float. It is held in place by a small pin that just pushes out. When the float comes out, watch out for the little valve you push to stop the fuel flow when the float is at the right level. It floats out. please clean
- If you look under the carb, you can see the most likely cause of the seizure, the jet. It looks like two screws with a hole in the middle. Spray a generous amount of carb cleaner (point the cleaner towards the jet) and let it soak in for a few minutes.
- Use an air line (or a can of pressurized air sold as an “air duster”) to blow the jet. Repeat the previous step and this step until the ganglion is no longer visible.
- Put the carb back in, put the fuel in and start the bike. I hope it clears the congestion and makes it as sweet as a nut.
