Is your car having startup or acceleration or idling problems? If the answer is yes to this question, then it might be because your carburetor is due for a cleanup. Carburetors in an engine do get clogged up with various impurities, and it is necessary to clean them at regular intervals to ensure that you get optimal performance.

To do that you would need a carburetor cleaner. But, which one should you be getting? That is what we will discuss in this article. Here we will talk about the 5 best carburetor cleaners for small engines. But, before that, let us discuss the factors that you should consider before getting a carburetor cleaner.

Things to consider before buying a carburetor cleaner:

When you are looking for the best carburetor cleaner for small engines, there are various things that you need to be careful of. This includes factors such as the type of cleaner, ease of use, and compatibility. Let us talk about these in detail. 

1. Chlorinated vs Non-Chlorinated

Chlorinated, and non-chlorinated are the two main types of carburetor cleaners out there. When it comes to the cleaning aspect, chlorinated cleaners work better, however, they are also harsher on certain materials. Non-chlorinated options are not as good as the chlorinated alternatives when it comes to cleaning, but with these, there is no harm to the delicate materials inside the carburetor.

2. Spray vs Dip

The carburetor cleaner can come either in the form of a spray or a dip. Both have their own merits and demerits. Sprays can be used without opening the carburetor, whereas dip requires you to open it up. But, in terms of cleaning, a dip is more effective.

3. Compatible 

Certain chemicals used might not be compatible with a specific material of your carburetor. So, it is essential to ensure that the chemicals are compatible with the material, and do not damage it.
