Removing a few more parts of the carburetor is essential to have proper access to the main parts so that you can clean them thoroughly.

Checking and cleaning

After checking the petcock, which makes the gas run in the vehicle, and turning it off, it will be time to move on to cleaning.

But before you step into the actual part of ATV carb cleaning without removing it, you should keep some paper towels, which should be useful. When you take the last part of the bowl off the base, some amount of gas might leak. 

Spray your branded cleaner inside the region where the bowl was present. After the first spray, you can then take a break. The parts removal steps were not very easy, so you deserve a break. 

Have some patience and put in a few sprays in a gap of five minutes so that the dirt and old grime become worn.

But after you take off the bowl, you might notice some float-ups. These float-ups arise when gas is present in the bowl and in large quantities. 

The vehicle system of ATVs is designed in a way that this kind of bowl state will automatically make the fuel valve close down.

When comparing reasons for the carburetor not to function right, the most probable reason is found to be a jet that is clogged up. Clogged jets also occur due to using the wrong gas, which is unsuitable for the type of ATV.

Ethanol gas is often the reason for clogged-up jets, but there might be other reasons too. Make use of the carb cleaner the same way in a gap of four minutes to make the jets clean.

Experts recommend using branded carb cleaner; you can find the right product by checking if it contains chlorine.

After you have completed the cleaning, let the carb be open in the previous state and not install all the parts. Letting the carb cleaner do its work by reacting with the accumulated dirt is very important. 

In the end, wipe with a clean cloth all over the carburetor. Then, slowly, one by one, reinstall all the parts, starting from the float to the bowl, air box, and other parts left.

But you can also keep the air filters unattached for the time being for testing the ATV. If everything seems fine after you take the ATV for a ride, you can return the air filters.
