To tune a Stihl chainsaw, you will need to check and adjust the carburetor, air filter, spark plug, and fuel lines. The carburetor regulates the mixture of air and fuel that goes into the engine. The air filter keeps dirt and debris from getting into the engine.
The spark plug ignites the mixture of air and fuel in the engine. The fuel lines deliver gasoline to the carburetor.
- Start by checking the chain tension
- The chain should have some slack, but shouldn’t be loose
- If the chain is too loose, it can come off of the saw while you’re using it
- If the chain is too tight, it will put unnecessary strain on the engine and potentially damage the saw
- Once you’ve checked and adjusted the chain tension, move on to sharpening the chain
- You’ll need a file or grinder specifically designed for chainsaws to do this properly
- First, find the cutting angle of your saw’s teeth using a gauge (included with most files and grinders)
- Next, use your file or grinder to sharpen each tooth at that angle until it’s nice and sharp again
- Be sure to keep an even pressure so that all of the teeth are uniform in shape and size
- Lastly, clean any debris from inside the bar casing with a brush or compressed air before putting everything back together again

How Do You Adjust the H And L on a Stihl Chainsaw?
If you need to adjust the H and L on your Stihl chainsaw, there are a few things you’ll need to do. First, make sure the chainsaw is turned off and the chain is not moving. Next, locate the screws that control the tension on the chain.
These screws are usually located near the front of the chainsaw, on either side of the bar.
To adjust the H screw, turn it clockwise to tighten the chain or counterclockwise to loosen it. To adjust the L screw, turn it counterclockwise to tighten the chain or clockwise to loosen it.
Once you’ve made your adjustments, start up the chainsaw and test it out to see if everything feels good. If not, make further adjustments as needed until you’re happy with how it feels.
How Do I Tune Up My Stihl Chainsaw?
If your Stihl chainsaw isn’t running as smoothly as it used to, it’s probably time for a tune-up. Luckily, this is a relatively easy process that you can do at home with just a few tools. Here’s what you’ll need to do to get your Stihl chainsaw back up and running like new:
1. Check the chain tension. The first step is to check the tension of your saw’s chain. If it’s too loose, it can cause the chain to come off while you’re using it.
To check the tension, simply pull on the bottom of the guide bar until there is about 1/4″ of play. If the chain is too tight, it can damage both the bar and the engine over time.
2. Sharpen the chain.
Next, you’ll need to sharpen the teeth on your saw’s chain using a round file or an electric sharpener. Be sure to match the size of file (or stone) to the width of your particular saw chain – using a larger or smaller one can damage the teeth. Start by filing each tooth down until it reaches its original shape (you should be able to feel when this happens), then move on to honing each tooth with a fine grit sharpening stone until it’s nice and sharp.
3. Clean or replace air filter In order for your engine to run properly, it needs clean air coming in through its filter – otherwise, debris and dust will clog up vital components over time and cause serious damage (not to mention decreased performance). Inspect your air filter regularly and clean or replace it as needed – depending on how often you use your saw, this may be every few months or so.
4 .
Clean spark plug Another important component in keeping your Stihl chainsaw running well is its spark plug – which helps ignite fuel in order for combustion to occur within the engine cylinder(s). Over time, however, deposits from fuel and oil can build up on spark plugs , causing them to “foul” (or become dirty). This not only makes starting harder but also decreases performance while running .
Inspecting and cleaning (or replacing) your spark plug regularly will help keep things running smoothly . Simply unscrew remove old plug , make note of any deposits/build-up , then either clean with wire brush before reinstalling OR install new plug .
How Do You Adjust the High And Low on a Stihl Carburetor?
If you need to adjust the idle speed on your Stihl chainsaw, it’s a pretty simple process. First, locate the screws on the carburetor that control the high and low settings. These are usually labeled “H” for high and “L” for low.
Next, use a screwdriver to turn each screw clockwise or counterclockwise until you achieve the desired result.
If you’re having trouble getting the right mixture of fuel and air, it might be helpful to consult your Stihl chainsaw manual. This will give you specific instructions on how to adjust the carburetor settings.
Why Does My Stihl Chainsaw Bog down When I Give It Gas?
If your Stihl chainsaw bogs down when you give it gas, there are a few potential causes. One possibility is that the air filter is dirty and needs to be cleaned or replaced. Another possibility is that the carburetor needs to be adjusted.
Finally, if the chainsaw is overworking, it may simply need more oil.
The first thing you should do if your chainsaw bogs down when you give it gas is to check the air filter. If the air filter is clogged, it will restrict airflow and cause the engine to bog down.
Clean or replace the air filter as needed.
Next, check the carburetor. If it’s not adjusted properly, it can cause the engine to bog down when you try to give it gas.
Adjusting the carburetor is a relatively simple process, but if you’re not familiar with how to do it, you may want to take your chainsaw to a qualified technician who can do it for you.
Finally, make sure that your chainsaw has enough oil. If it doesn’t have enough oil, this can also cause the engine to bog down when you try to give it gas.

Tuning a Chainsaw With a High And Low Setting
If you’re like most people, you probably don’t think much about the inner workings of your chainsaw. But if you want to keep your saw in good working order, it’s important to know a thing or two about tuning. In this blog post, we’ll walk you through the process of tuning a chainsaw with a high and low setting.
We’ll start with the high setting. To adjust the high setting, start by loosening the adjusting screw on the side of the carburetor with a screwdriver. Then, turn the screw clockwise until it stops.
Next, turn the engine over until it starts and let it run for a few minutes. After that, turn off the engine and check the spark plug. If it’s black or sooty, turn the adjusting screw counterclockwise until the soot clears up.
Now let’s move on to the low setting. The low setting controls how much fuel is delivered to the engine at idle speed. To adjust it, start by loosening the adjusting screws on both sides ofthe carburetorwith a screwdriver.
Then, turn one ofthe screws clockwise until it stops and leavethe other one untouched . Finally , restartthe engineand letit idle fora few minutes . Checkthe sparkplug againand readjustif necessary .
That’s all there is to tuning a chainsaw with a high and low setting! By following these steps, you can be sure that your saw is running at peak performance.
Stihl Chainsaw Carburetor Adjustment Screws
If your Stihl chainsaw starts to run a little bit rough, it might be time for a carburetor adjustment. The carburetor is responsible for mixing the air and fuel in the correct ratio, so if it’s not set correctly, your saw won’t run as efficiently as it should.
There are two screws on the carburetor that you can adjust – the idle screw and the high speed screw.
The idle screw controls how much fuel is mixed with air at low speeds, while the high speed screw does the same thing at higher speeds.
To adjust these screws, you’ll need a special tool called a carburetor adjusting tool. This looks like a long, thin shaft with a small knob on one end.
Once you have this tool, follow these steps:
1) Warm up your saw by letting it run for a few minutes. This will help ensure that all of the parts are warm and expanded so that they’re working correctly.
2) Turn off the saw and remove the spark plug boot (the rubber cap that goes over the spark plug). This will give you access to the spark plug itself.
3) Use your carburetor adjusting tool to turn both screws clockwise until they’re lightly seated against their stops.
Don’t overtighten them!
4) Now turn each screw counter-clockwise 1 1/2 turns – this is where you’ll start making your adjustments from.
5) Start up your saw and let it idle for a minute or so.
If it’s running too fast, turn the idle screw clockwise until it slows down to an acceptable speed. If it’s running too slow or dies entirely, turn the idle screw counter-clockwise until it picks back up again. Repeat this step until you have achieved an acceptable idle speed .

How to Adjust a Chainsaw Carburetor from Scratch
If your chainsaw is having trouble starting, or is running rough, the carburetor might be the problem. Fortunately, you can adjust a chainsaw carburetor yourself, and it’s not as difficult as you might think. In this article, we’ll show you how to adjust a chainsaw carburetor from scratch.
Before you start adjusting the carburetor, make sure that the saw is turned off and that the chain is not moving. Then, remove the air filter cover and unscrew the two screws that hold the carburetor in place. Next, locate the three adjustment screws on the side of the carburetor – these are typically labeled L, H, and T.
To begin adjusting the carburetor, turn all three screws clockwise until they’re tight against their stops. Then, turn each screw counterclockwise 1/2 to 1 turn. After making these adjustments, start up your chainsaw and see how it’s running.
If it’s still running rough or won’t start at all, you may need to further adjust one or more of the screws.
Once you get your chainsaw running properly again, be sure to check and clean the air filter regularly – a dirty air filter can cause many of the same problems as a poorly adjusted carburetor.

How to Adjust the Carburetor on a Stihl Ms170 Chainsaw
If you’re having trouble with your Stihl MS170 chainsaw, one possible issue could be the carburetor. This guide will show you how to adjust the carburetor on your MS170 so that it’s running properly again.
Before making any adjustments to the carburetor, always check the air filter and spark plug first.
If they’re dirty or damaged, they could be causing problems with the engine. Once you’ve ruled those out, then you can move on to adjusting the carburetor.
There are two screws on the back of the carburetor that control fuel mixture: The L-screw adjusts idle speed and governs how much fuel is mixed with air when the engine is idling.
The H-screw adjusts high speed mixture and controls how much fuel is mixed with air at higher speeds.
To adjust the L-screw, turn it clockwise to increase idle speed or counterclockwise to decrease idle speed. To adjust the H-screw, turn it clockwise to lean out the mixture or counterclockwise to richen up the mixture.
It’s usually best to start with small adjustments and work your way up until you find what works best for your saw.
Once you’ve made your adjustments, start up the saw and let it run for a few minutes so that everything can settle into place. Then recheck your work by putting it under load (cutting something) and see how it responds.
If necessary, make further adjustments until everything is running smoothly again.
Chainsaw Adjustment Screws
Chainsaws are one of the most versatile tools in a homeowner’s or handyman’s arsenal. They can be used for everything from trimming trees to cutting firewood, and they’re relatively easy to operate. However, like any tool, chainsaws require periodic maintenance to keep them running smoothly.
One of the most important things you can do to maintain your chainsaw is adjust the tension on the chain. This is accomplished by adjusting two screws – the master link screw and the side plate screw.
The master link screw is located on the bottom of the saw near the front, and it controls the tension on the drive link (the part of the chain that fits into the bar).
The side plate screw is located on top of the saw near the rear, and it controls tension on both outer links (the parts of chain that wrap around either end of bar). Both screws should be checked frequently and adjusted as needed to ensure that your chainsaw runs properly and doesn’t throw off sparks or kickback unexpectedly.
To adjust either screw, start by loosening it until there is some slack in the chain.
Then, turn it clockwise until there is slight resistance; you don’t want to overtighten these screws or you could damage your chainsaw. Check both screws periodically – at least once per week if you use yourchainsaw regularly – to make sure they are tight enough but not too tight. With a little bit of care and attention, you can keep your chainsaw running smoothly for years to come!
Chinese Chainsaw Carburetor Adjustment
If you have a Chinese chainsaw, chances are that it came with a carburetor that was not properly adjusted for your particular saw. In this blog post, we’ll show you how to adjust the carburetor on your Chinese chainsaw so that it runs more efficiently and doesn’t overheat.
The first thing you’ll need to do is locate the adjustment screws on the side of the carburetor.
There are usually two screws, one for idle speed and one for fuel mix. The idle speed screw controls how fast the engine runs when idling, while the fuel mix screw adjusts the ratio of fuel and air being mixed in the carburetor.
To adjust the idle speed, turn the idle speed screw clockwise to increase engine speed or counterclockwise to decrease engine speed.
To adjust the fuel mix, turn the fuel mix screw clockwise to lean out the mixture or counterclockwise to richen up the mixture.
Make sure to test your saw after making any adjustments to ensure that it’s running properly and not overheating. With a little bit of trial and error, you should be able to get your Chinese chainsaw running like new!
Conclusion
If you’re a Stihl chainsaw owner, you know that these saws are built to last. But like any other piece of machinery, they require periodic maintenance to keep them running smoothly. One of the most important aspects of maintenance is keeping the chain sharp.
A dull chain not only makes sawing more difficult, it can also be dangerous. In this post, we’ll show you how to tune your Stihl chainsaw so that it’s always ready for action.
First, check the bar and chain for damage or wear.
If either the bar or chain is damaged, replace it with a new one. Next, clean the bar and chain with a degreaser or solvent-dipped rag. Be sure to remove all dirt and debris from both the bar and chain before moving on.
Once the bar and chain are clean, it’s time to sharpen the chain. You can do this yourself with a round file or have it done professionally at a certified Stihl dealer . If you’re going to sharpen the chain yourself , make sure to use a file guide to ensure that each tooth is sharpened evenly .
After sharpening , inspect the depth gauges on each tooth of the cutter . The depth gauges should be set at 1/8 inch (.325 cm) for most cutting applications . If they’re not , use a flat file to adjust them accordingly .
Now that your Stihl chainsaw is properly tuned , you can get back to work feeling confident that your saw will perform its best .
