How to Clean a Craftsman Lawn Mower Carburetor
Basically, carburetors mix air and fuel so they can be provided to the engine for combustion. Fuel deposits and debris get stuck in the carburetor jets as a result of using substandard fuel and not maintaining the vehicle regularly. Because of this, the performance of the engine is reduced. Due to the added parts/components, riding lawnmowers require more maintenance than usual.

It is possible for old or contaminated fuel to create a sticky residue inside the carburetor of the lawnmower. In some cases, this causes a clog or restriction that makes it difficult for the right mixture of air and fuel to enter the engine. In many cases, cleaning the carburetor will fix the problem when a person refers to it as “dirty.” Use this guide to learn how to diagnose and clean a lawnmower carburetor.
How to Clean a Craftsman Lawn Mower Carburetor
A restricted carburetor or a dirty carburetor can be easily diagnosed. In addition to causing any of the following problems, it can also cause the following problems:
- An obvious increase in gasoline consumption while using the lawnmower.
- Lawn mower not starting when turned on.
- Smoke coming out of the muffler area that is black in color.
- In grass cutting, an engine may start but stall.
- When the mower is running, it runs roughly.
We will discuss in-depth ways of cleaning the carburetor but let’s first focus on preventing these kinds of problems. The most simple way to avoid a dirty carburetor is to make sure the fuel is fresh when you fill the tank. Stabilizing the fuel or adding a fuel stabilizer is also a useful option. Clean the carburetor if it becomes clogged How to Clean a Craftsman Lawn Mower Carburetor.
Carburetor photos of Craftsman mowers
A cell phone is usually nearby for most people. The phone probably has a camera that makes taking photos quick and easy. You should use one of these to document your steps if you have one.
Even if you have a sharp memory, I highly recommend you capture multiple photos of the carburetor during and before teardown.
The number of small parts you will work with will be considerable. For your carburetor to be put back together properly, you will need a photo guide. Having these photos is better than not having them at all because you may not need them.
How to clean a lawnmower carburetor
You want to make sure you are completely safe before beginning the cleaning process. If you are cleaning the lawnmower, it should have a cool engine. Get close to the carburetor by setting the lawnmower on a flat surface and removing the engine cover. Keeping these things in mind will help you avoid injuries or damage to the carburetor. You can now begin the cleaning process.
The tools you’ll need include a socket set, a nut driver, needle-nose pliers, clamps, an adjustable wrench, and screwdrivers. The carburetor rebuild kit, plastic gloves, and carburetor cleaner can also be carried along.
Confirm that the problem arises from the carburetor before you begin taking it apart. Check to see if the fuel valve is running, if the spark plug is working, and if the fuel tank has gas. Spritz an aerosol cleaner or carburetor cleaner inside the carburetor. There is a fuel issue when the engine starts, sputters, then dies. You will need to follow these steps if there is a more serious problem.
You need to remove the bowl of your Craftsman mower carburetor
The bowl should be located at the bottom of your carburetor. This is where a small amount of fuel is collected once it is released from the fuel tank. Soak up any remaining fuel in the bowl with a rag.
The bowl can be removed from the carburetor by removing the screw at the base. Gaskets are located around the bowl. A rubber band resembles it.
Do not use carburetor cleaner on the gasket or any other substance that may ruin it. In that case, you must replace the gasket before reattaching the bowl.
When cleaning fails, replace or rebuild your Craftsman carburetor
There are times when cleaning the carburetor won’t solve the problem. It is possible that small parts of your carburetor need to be replaced, or old fuel has caused so much damage you must replace it.
It is necessary to rebuild or replace the carburetor. If you want to ensure you order the correct part(s), you need to have your engine model and specs on hand. Among the small engines used in Craftsman’s mowers are those from other manufacturers.
Ordering a replacement carburetor or rebuild kit online, through your local Craftsman dealership, or from an authorized engine dealer is easy.
Make sure the main jet and bowl nut are clean
Bowl nuts are located under the carburetor. Remove them. The nut secures the bowl to the pump and is the main jet that draws fuel, so it’s the most likely to clog. You should use a thin metal wire to remove these deposits from the jet. Make sure the jets are clean by spraying carb cleaner on them.
The cleaner’s smell will let you know when it’s unclogged once you see fumes coming out. There is also debris, rust, and deposits in the bowl. The bowl can be cleaned by spraying it with a cleaner.
Cleaning a carburetor: how do you know?
If you see the following signs on your vehicle, your carburetor needs a thorough cleaning:
The first. Despite priming the engine several times with gas, the engine will not start.
The second. The engine stalls, so it stops after starting. A dirty carburetor will cause this problem.
The third is lean: When the quantity of fuel in the air-fuel mixture is low, the engine makes a popping sound at the intake. It is the result of carburetor blockages causing a lean condition.
The fourth. The opposite of running poorly is running rich. The engine produces black smoke when the carburetor is flooded with gasoline.
The fifth. Deposits clog the needle when it’s flooded. A large amount of fuel flows into the carburetor, resulting in flooding.
Conclusion:
When engines are not maintained properly, faulty carburetors result. The carburetor, filters, and plugs can become clogged when they are not serviced at the right time. Further, check a lawnmower’s fuel quality to prevent deposits from forming from poor-quality fuel. A lawnmower’s fuel tank should not be stocked with gasoline for more than 30 days. A fresh supply of fuel should be added to the tank regularly. Otherwise, you can also use a fuel stabilizer if you plan to store your mower for an extended period of time.
