So, the question arises, how one can clean the carburetor. Well, it is very easy to clean carburetor, and today we will discuss about how to clean carburetor on pressure washer.

The Function of a Carburetor

A carburetor is used in a gas-powered pressure washer. It has no existence in an electrical pressure washer. First, let us tell you what a carburetor is. A carburetor is the generator of a pressure washer.

Gas-powered pressure washer burns fuel when they run. The carburetor provides enough air to mix with the fuel and burn so that the pressure washer can function effectively. Again, the ratio of air to fuel should be ideal for the pressure washer to function effectively.

The ratio should be 15:1 or 12:1. Whenever there is a malfunction in the carburetor, the fuel burns more than usual. It is because the carburetor gets clogged, and that is when the carburetor needs to get cleaned.

Symptoms of Clogged Carburetor

A clogged carburetor will not function properly. And it’s crucial to keep it cleaned religiously. People tend to ask how they will know that the carburetor is clogged. Well, there are some very common symptoms that a carburetor shows when it is clogged. They are stated below:

Does not start:

When the carburetor is clogged, firstly, it does not start. A clogged carburetor does not let air pass to mix with the fuel, and when there is no air, the fuel inside cannot burn.

Unwanted sounds:

Carburetors tend to produce unwanted sounds when there is an imbalance of air and fuel. As we mentioned earlier, there is an ideal ratio of air to fuel for the carburetor to function. When this ratio gets messy, the carburetor produces a different unwanted sound, which is very irritating for the user.


Sometimes, there can be a block in the valve, which does not let the fuel holder close on time. For this reason, there’s happened an overflow of felt that is liable for leakage.

Black smoke:

The carburetor produces black smoke from the exhaust when it is clogged. This black smoke is produced when the amount of fuel crosses the maximum capacity of the carburetor. Moreover, when the carburetor is clogged, the pressure washer burns more fuel than usual. That is why this black smoke is caused.


Backfiring is another common symptom of a clogged carburetor. If the carburetor has an unideal mixture of air and fuel, it tends to get overheated. This can heat the whole pressure washer and can cause harm to the engine of the pressure washer.

Malfunctioned engine:

Clogged carburetor does not let the engine function properly. As there is an imbalance in the mixture of air and fuel, it is very normal that the engine will not function at its best. Hence, a clogged carburetor results in a malfunctioned engine.

Why the Carburetor Gets Clogged?

If the carburetor is clogged, then the pressure washer won’t start. It is very important to know why the carburetor gets clogged because when you know the reason for the damage, you will be able to protect it. On the other hand, the proverb goes, “Prevention is better than cure.”

The carburetor gets clogged when the fuel is kept in the pressure washer for a long period. When the fuel burns, it creates some dirt, which eventually clogs the carburetor.
