One of the most important parts of a lawn mower is the carburetor. It is vital to keep it clean because if it’s not, the engine will malfunction and you could risk injury or death. When your lawnmower is turned off, make sure to check the gas filter before you turn it back on. If debris has come in contact with the filter, it will inhibit airflow.

Lawn mowers are great for giving you the lawn of your dreams. However, when they start to get dirty and used more, they require some TLC. Let’s take a look at how to clean your lawn mower.

The first thing you want to do is run the mower until it dies down so that any loose dirt can fall out of the engine. Next, remove any debris from the mower deck before proceeding with the next steps.

What is a carburetor?

A carburetor is a device that mixes air and fuel with an internal combustion engine. They are found in most engines today. The carburetor is designed to deliver the correct amount of air, fuel, and air/fuel mixture to the engine. It delivers the correct mixture by mixing gasoline with air in the intakes. 

It has many parts that need to be maintained, especially when it comes to cleaning them.

What tools are needed

A common question for homeowners with a lawn mower is “What tools are needed to clean the carburetor?” Carburetor cleaner spray, which is composed of water and petroleum-based solvents, should be sprayed into the carburetor. Sometimes additional parts may need to be disassembled, such as the gas filter or fuel line. For small engines use an approved nozzle to avoid accidental spilling.

If you are trying to get your hands dirty, you should know what tools are necessary to clean the carburetor on a lawn mower. You will need an adjustable wrench, socket set, screwdriver, crescent wrench, and at least one gas line cleaner. The carburetor is usually located near the air filter and might be covered by a small plastic cover. Remove this cover before dismantling the carburetor.

Prepare for the process

A lawn mower is a great tool for homeowners to use to keep their yards looking neat and tidy. Occasionally, there are times when the lawn mower will have to be cleaned. Cleaning the carburetor is one of the steps in this process.

The first step is to remove any excess fuel left over from the last time the lawnmower was run.

Step by step instructions on how to clean the carburetor

Carburetors are small machines that convert gasoline to vapor, which in turn is used to mix with the outside air to create power. They are small enough that they can be held by a hand, but also large enough that should they malfunction, it could lead to major issues. The process of properly cleaning a carburetor is very technical and should not be attempted without the proper training and equipment.

Clean Off Any Dirt

You can clean off any dirt or dust on the carburetor with a vacuum cleaner. Removing the dirt and dust will improve the performance of your vehicle. The cleaner you use should be made for cleaning carburetors; otherwise, you could end up damaging your vehicle. A clean carburetor will help to keep your vehicle running better and last longer.


Carburetors can collect gunk over time which needs to be cleaned out before the vehicle will run right. Gunk in carburetors can interfere with gas flow and cause major engine performance problems. The gas pump is one of the most common sources of gunk in carburetors, so it’s important to avoid exposing your carburetor to gasoline when cleaning it. There are steps that you can take to clean out your carburetor without using gasoline.

Clean Off Any Rust

Many people are often surprised to learn that carburetors need cleaning just like any other component of the car. Rust, debris, and particles will build upon the inside of the carburetor over time. This buildup can cause poor performance, which can lead to more costly repair costs. Luckily, it is relatively easy to clean off the rust and debris from a carburetor using a few household items.

Clean Out The Inside Of The Carburetor

Every car needs a tune-up every few thousand miles. You can buy a kit at your local auto parts store that will have everything you need to do the job. It is best to put the project off as long as possible because it is not an enjoyable process. The carburetor collects dirt and grease over time so it is important to clean out the inside of it periodically, especially before storing the vehicle for an extended period of time.

Clean Out The Gas Tank

The lawn mowing season is in full swing, and for many people, that means starting up the old lawn mower after a storage break over the winter. Clearing out the gas tank to clean the carburetor on lawn mower is an important step before using your lawn mower again. If you have not used your mower at all during the winter, it will be crucial to clear out any substance that has built up in the model or tank of your engine.

Put Everything Back Together

If you have a problem with your lawn mower and want to make sure that it starts up properly, sometimes all you need to do is put everything back together and clean the carburetor. This can be done by removing the air filter and bowl on top of the engine and accessing the carburetor which will likely be found on the side of the engine.


In conclusion, cleaning the carburetor on your lawn mower is easy, but it does require time and attention to detail. You can use a variety of techniques for this job, but the most common are the wire brush, clean cloth, spray cleaner, and compressed air. The most important thing to remember is safety. Make sure you wear gloves and goggles before beginning. Furthermore, always be mindful of what chemicals you are using because some are toxic or flammable.
