Cleaning a chainsaw carburetor step by step

Step 1 – Check the air filter

The prime duty of a carburetor is to supply gas to the engine to make the tool work. It helps to mix a little fuel with the air that makes its way to the engine. Therefore, the first step is to check the air filter. Dirt can easily clog up the air filters that disturb the smooth performance of the tool.

Step 2 – Clean or replace

You can simply clean the air filter to get rid of the dirt and dust. If the filter is not in a good condition and needs a replacement, you can simply replace it.

Step 3 – Remove and drain the carburetor

In this step, you will need to remove the carburetor and drain it properly. You may see some brown or yellowish gummy-like stuff inside the carburetor that needs to be cleaned.

First, you can clean the outer part of the carburetor using a brush and a cleaner especially made for cleaning the carburetors. You can follow any professional tutorial to make one yourself or you can purchase a good one from stores.

Next, remove the parts in order so you can clean them and reassemble them again accordingly. The parts include the diaphragm, needle adjusters, and a cover plate. Make sure that you clean all the holes and corners thoroughly. Repeat the same step with air intake so you can clean the throttle. Now it’s time to reassemble everything in order.

How to adjust a carburetor on a chainsaw

Step 1

The first step is warming up the carburetor. For this, you’d need to start the motor and let it run for a few minutes so the saw can warm up a bit.

Step 2

Once it warms up a bit, turn the motor off and let it rest for half a minute. After that, pick the saw up and point it forward. Now you can proceed to the next step if the tool is still running.

Step 3

If it’s not and stalling instead, you need to make sure that the speed screw is tightened up ( this is to decrease the amount of fuel that enters the carburetor) and then repeat step 2 as much as needed.

Step 4

In this step, you need to speed up the idling saw. If it speeds up right, you can proceed to the next step.

Step 5

If it does not, you need to loosen up the low-speed screw ( this is to increase the amount of fuel that enters the carburetor) and repeat step 4.

Step 6

Now it’s time to speed up the idling saw again but this time it’s only for five seconds. Note that you can’t speed it up for 10 seconds or more than that. It needs to flutter during the process for you to move into the next step.

Step 7

If the tool screams instead, loosen up the high-speed screw and repeat the previous step.

Step 8

If the chain stays motionless when the saw is idling, you’re done. But if it still rotates, you need to move on to another step.

Step 9

You need to adjust the idler screw as needed to stop the rotating. This won’t take much time but only a few seconds but this needs to be corrected.

All these steps take only a few minutes in total. So it’s clear that adjusting your chainsaw carburetor is a very easy process and does not require much time. But this little effort will help you greatly in the long run and ensure effective results. You’ll soon realize that you don’t need to put much force to get your job done. The tool will be so fast and smooth that you’ll enjoy working with it even more than before.
