Best Guide on How to clean a chainsaw carburetor- 2022

If your chainsaw’s carburetor is dirty, it can cause all sorts of problems. The most common issue is that the engine will run poorly or not at all. In this article, we’ll show you how to clean a chainsaw carburetor in just a few simple steps.

A chainsaw carburetor is responsible for mixing the air and fuel in the correct ratio before it enters the engine. Over time, this mixture can become unbalanced, causing the engine to run poorly or even fail to start. The good news is that cleaning a chainsaw carburetor is a relatively easy task that anyone can do with the right tools and a little know-how.

Here’s what you’ll need to clean your chainsaw carburetor:

  • Phillips head screwdriver
  • Flathead screwdriver
  • Needle nose pliers
  • Carburetor cleaner (or white vinegar)
  • Rags or paper towels
  • Toothbrush (optional)

First, you’ll need to locate the carburetor on your chainsaw. It’s typically located near the engine and will have a small fuel line running to it. Once you’ve found the carburetor, you’ll need to remove the air filter. This is typically located on the side of the chainsaw and can be removed by unscrewing a few screws.

With the air filter removed, you should be able to see the carburetor. There will be a few different types of screws holding it in place. Use the Phillips head screwdriver to remove these screws, and set them aside in a safe place.

Once the carburetor is loose, you can remove it from the chainsaw. Be careful not to lose any of the small parts or gaskets that may be attached to it.

Symptoms of a Bad/Dirty Carburetor, some helpful tips

Reduced engine performance

If you notice a sudden drop in your Chainsaw’s power or it fails to start at all, the first thing you should check is the carburetor. A dirty or failed carburetor is one of the most common reasons for reduced engine performance.

Engine runs erratically

Another common symptom of a bad carburetor is an engine that runs erratically. If your chainsaw’s engine is sputtering or stalling, it’s a good indication that the carburetor is dirty or needs to be adjusted.

Black smoke from the exhaust

If you notice black smoke coming from the exhaust, it’s a sign that the carburetor is running too rich (meaning there’s too much fuel in the mixture). This can be caused by a dirty carburetor or an issue with the fuel line.

Backfiring and overheating

If your chainsaw backfires and/or overheats, it’s a strong indication that the carburetor needs to be cleaned or replaced.

Hard to start

A chainsaw that’s hard to start is another common symptom of a dirty carburetor. If you’ve checked all the other possible causes and you’re still having trouble starting your chainsaw, it’s time to clean the carburetor.

Step by Step Procedure for how to clean a chainsaw carburetor

The carburetor of your chainsaw can be cleaned in simple steps:

Clean the Air Filter

Whenever trying to clean or fix anything on your Chainsaw, it is important to first start with the air filter. A chainsaw’s air filter prevents dirt and dust from entering the engine, and over time it can become clogged with debris. This can restrict airflow to the carburetor, causing the engine to run lean (meaning there’s not enough fuel in the mixture).

To clean the air filter, simply remove it from the chainsaw and tap it gently on a hard surface to remove any dirt or debris. If it’s severely clogged, you can rinse it with water and let it air dry before putting it back on the chainsaw.

Clean the Carburetor’s Intake Components

After ensuring that the air filter is in good working order or that it has been cleaned, the next step is to remove the carburetor from the chainsaw. This will give you better access to all of the carburetor’s parts so that you can clean them more thoroughly.

To remove the carburetor, first, locate the screws that hold it in place (typically two or three). Use a Phillips head screwdriver to remove these screws, and set them aside in a safe place.

Once the carburetor is loose, you can pull it away from the chainsaw. Be careful not to lose any of the small parts or gaskets that may be attached to it.

Clean/Wash the Carburetor’s Needle Valves

The needle valves are located on the side of the carburetor and are responsible for regulating the flow of fuel into the engine. Over time, these valves can become clogged with dirt and debris, which can restrict fuel flow and cause engine performance issues.

To clean the needle valves, use a small brush (toothbrush or cotton swab) to remove any dirt or debris that may be clogging them. Once they’re clear, you can reassemble the carburetor and put it back on the chainsaw.

Clean/Wash the Carburetor’s Bowl

The carburetor bowl is located under the needle valves and collects any fuel that isn’t used by the engine. This fuel can evaporate over time, leaving behind a sticky residue that can clog the carburetor.

To clean the carburetor bowl, remove it from the carburetor and rinse it with water. Be sure to remove any dirt or debris that may be stuck to the bottom of the bowl. Once it’s clean, you can reattach it to the carburetor and put the carburetor back on the chainsaw.

Work the Pull Cord

Add some drops of a cleaning agent to the fuel tank of the chainsaw. Cleaning agents will help to remove any debris or sludge that has built up in the fuel lines.

After adding the cleaning agent, work the pull cord a few times to circulate the cleaner through the fuel system. Then, let the chainsaw sit for a few minutes before starting it up again.

Drain the Old Fuel and Add Fresh Fuel

If your chainsaw has been sitting for a while, the fuel has likely gone bad. Old fuel can clog the carburetor and cause engine performance issues. To avoid this, be sure to drain the old fuel out of the tank before adding fresh fuel.

To do this, remove the fuel cap and carefully tilt the chainsaw so that the fuel drains out. Once the fuel has drained, you can add fresh fuel to the tank and replace the fuel cap.

Adjust the Carburetor’s Settings

Once you’ve cleaned all of the carburetor’s parts, it’s important to adjust the settings so that the engine will run properly. The most common adjustment is the idle speed, which can be increased or decreased depending on the needs of the engine.

To adjust the idle speed, locate the screws that control it (usually labeled “L” and “H”). Use a flathead screwdriver to turn these screws until the desired idle speed is achieved.

It’s also important to check the carburetor’s air/fuel mixture. This can be done by removing the spark plug and inspecting it. If the spark plug is white or light gray, the mixture is too lean; if it’s black or sooty, the mixture is too rich.

To adjust the mixture, locate the screws that control it (usually labeled “L” and “H”). Use a flathead screwdriver to turn these screws until the desired mixture is achieved.

Once the carburetor is properly adjusted, you can replace the spark plug and reassemble the chainsaw.

Here are some helpful hints

Assume your chainsaw’s carburetor is not being cleaned in a long time. The best way to clean the carburetor of the chainsaw is to remove it but if you do have time to remove the carburetor you can clean the chainsaw carburetor without removing it. Regular cleaning of the carburetor is essential to keeping your chainsaw in optimal running condition and preventing long-term damage.

You’ll need a carburetor cleaner liquid to clean a carburetor without having to remove it. The following is the cleaning procedure:

Blend the Cleaner With Gasoline

Pour the carburetor cleaning liquid into a gas can. Next, add fresh gasoline to the can until it’s full. Swirl the can around so that the cleaner and gasoline are mixed.

Spray the Cleaner Into the Carburetor

Remove the chainsaw’s air filter cover and spark plug boot. Then, place the chainsaw so that the carburetor is pointing up.

Next, take the carburetor cleaner and gasoline mixture, and spray it into the carburetor until the carburetor is full. Be sure to cover all of the openings in the carburetor so that the cleaner can reach all of the dirty parts.

Run Your Chainsaw at an Idle or Slow Speed

After you’ve sprayed the carburetor cleaner into the carburetor, start the chainsaw and let it run at an idle or slow speed for a few minutes. This will allow the cleaner to work its way through the carburetor and clean all of the dirty parts.

If your chainsaw has an adjustable throttle, set it to the lowest setting so that the engine doesn’t rev too high.

Shut Off the Chainsaw and Let It Sit

Once the chainsaw has been running for a few minutes, shut it off and let it sit for a few more minutes. This will give the carburetor cleaner time to work its way through the carburetor and clean all of the dirty parts.

After a few minutes have passed, restart the chainsaw and let it run at an idle or slow speed for another few minutes.

Clean the Pilot Air Jet

Shut off the chainsaw and let it cool down. Then, remove the air filter cover and spark plug boot. Next, place the chainsaw so that the carburetor is pointing up.

Take the carburetor cleaner and gasoline mixture, and spray it into the carburetor until the carburetor is full. Be sure to cover all of the openings in the carburetor so that the cleaner can reach all of the dirty parts.

Now, locate the pilot air jet (this is a small hole located near the bottom of the carburetor). Take a small wire and insert it into the pilot air jet to clean it out.

Restart the chainsaw and let it run at an idle or slow speed for a few minutes. This will allow the cleaner to work its way through the carburetor and clean all of the dirty parts.

Once the chainsaw has been running for a few minutes, shut it off and let it sit for a few more minutes. This will give the carburetor cleaner time to work its way through the carburetor and clean all of the dirty parts.
