Is there anything in your house that doesn’t need maintenance? Similarly, every machine demands regular maintenance to stay efficient. 

Some of you might know a snow blower as a snow thrower. In simple words, it is a machine used to remove snow from the places where it causes trouble. 

The concept of a snow blower is that it eliminates the snow with the help of tools and carries it away to some other location instead of simply blowing it by air.

In a snowblower, a carburetor is a part of the motor to combine fuel and air for combustion. It is a device for supplying a spark-ignition engine with the mixture. 

It is an essential tool for the snowblower to run. If it is not maintained correctly, it shall create trouble in the machine’s appropriate functioning.

Even for the snow blower to function correctly, you need to clean its carburetor. You might think that it is a long and challenging process, but trust me, it is not. You can clean the carburetor without even removing it. Doesn’t it sound like a quick process, then?

With the regular use of the snowblower, you will undoubtedly face a few issues. That is normal with all the machines. Cleaning the carburetor might help resolve some of them. But how do you know when to clean it?

You will know that the carburetor is ready to be cleaned when you start facing specific issues like rough idling, stumbling while accelerating, increased fuel consumption, or flooding. These issues arise because the carburetor fails to function correctly. It is because of the debris that blocks the fuel and the air from getting it to the engine.

Things to Take Care of Before Cleaning a Carburetor

But before you start, make sure you get your hands clean on these things. Firstly, check the user manual and check the air filter. If your air filter is dirty, it will prevent the clean air from getting into the snowblower. As a result, it won’t function well.

Even if you clean the carburetor and the dirty air filter, the dust will enter the snowblower and eventually get to the carburetor. So, it would help if you cleaned the air filters first to prevent this from happening.

Focusing only on the cleaning part is not enough. You need to get the required materials before you start the cleaning process. Get the right tools, including a socket wrench, a piece of copper wire, compressed air can, wired brush, and liquid carburetor cleaning solution. You will need them while cleaning the carburetor to make your task easier.

Once you gather these tools, follow the steps below, and you are good to go.

If your snowblower is new, then your gaskets will be fine, and you need not worry about it. But if you have used your snowblower for a more extended period, then there might be a need to get new gaskets for the bowl and bolts.
