There are four screws on the body of most Stihl chainsaws. Two of these screws are used to adjust the idle speed and mixture, while the other two are for fine-tuning the carburetor. The two adjustment screws for idle speed and mixture are located next to each other, while the fine-tuning screws are on opposite sides of the carburetor body.
To adjust the idle speed, turn the screw labeled “L” clockwise to increase speed or counterclockwise to decrease speed. To adjust the mixture, turn the screw labeled “H” clockwise to lean out the mix or counterclockwise to richen it up.
- Check the owner’s manual for your specific model of Stihl chainsaw to find the correct idle speed setting
- Locate the carburetor adjustment screws on the body of the carburetor
- Turn the “L” screw clockwise or counterclockwise until you hear the engine begin to slow down
- Adjust the “H” screw in the same manner as the “L” screw until you reach the desired maximum RPMs

How Do You Adjust the H And L on a Stihl Chainsaw?
If you’re having trouble starting your Stihl chainsaw, or if it’s running unevenly, one potential issue is that the carburetor isn’t adjusted properly. The carburetor controls the mixture of air and fuel that goes into the engine, so it’s important to make sure it’s set correctly. Fortunately, adjusting the carburetor on a Stihl chainsaw is a simple process that only takes a few minutes.
To adjust the H and L settings on your Stihl chainsaw, start by locating the screws on the side of the carburetor. The H screw controls the amount of fuel that goes into the engine, while the L screw adjusts the idle speed. To increase either setting, turn the screw clockwise; to decrease it, turn counterclockwise.
It’s important not to adjust both screws at the same time, as this can throw off the balance of air and fuel in your engine. Make small adjustments until you find a setting that works for you. If your chainsaw is still having issues after adjusting the carburetor, consult a professional for further assistance.
How Do You Adjust H And L Screws on a Carburetor?
Most carburetors have two screws: the idle mixture screw (also called the pilot screw) and the main mixture screw. The idle mixture screw adjusts the amount of fuel that flows to the engine at idle. The main mixture screw adjusts the amount of fuel that flows to the engine at higher speeds.
To adjust the screws, turn them clockwise to lean out the mixture or counterclockwise to richen it. Start with both screws turned all the way in, then back them out 1/2 turn. Adjust one screw at a time, then test drive the car and see how it responds.
If it’s too rich or too lean, make another adjustment until you find the sweet spot.
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 carburetor adjustment screws on the back of the saw. There are two screws, one for low speed and one for high speed.
To adjust the low speed, turn the screw clockwise to increase the idle speed or counterclockwise to decrease it. For high speed, turn the screw counterclockwise to decrease the engine speed or clockwise to increase it.Keep in mind that these adjustments should be made very slowly and only in small increments until you find the ideal setting for your saw.
Also, be sure to check your owner’s manual before making any adjustments to ensure that you’re not accidentally damaging your saw.
How Do You Adjust the Mixture Screws on a Chainsaw?
Assuming you are talking about a 2 stroke chainsaw, the mixture screws adjust the fuel to air ratio. Too much fuel and not enough air will cause the engine to bog down and run rich. Not enough fuel and too much air will cause the engine to run lean and could damage the engine.
The mixture screws are usually located on the carburetor and have a spring next to them. To adjust them, turn them in (clockwise) to lean out the mixture or turn them out (counter-clockwise) to richen it up.

Stihl Factory Carb Settings
If you’re a fan of keeping your lawn looking neat and tidy, then you know the importance of having a good quality trimmer. Stihl is one of the leading manufacturers of trimmers and other lawn care equipment. In order to keep your Stihl trimmer running properly, it’s important to know the correct carb settings.
The carburetor on your Stihl trimmer controls the mixture of air and fuel that enters the engine. If this mixture is not correctly balanced, it can cause your engine to run poorly or even damage it over time. Therefore, it’s crucial to adjust the carburetor on your Stihl trimmer regularly in order to maintain peak performance.
There are three main screws that control the carburetor on a Stihl trimmer: idle speed screw, low speed screw, and high speed screw. The idle speed screw regulates how much air flows into the engine at idle. The low speed screw regulates how much air flows into the engine at low speeds.
And finally, the high speed screw regulates how much air flows into the engine at high speeds.To adjust these screws, first locate them on the side of the carburetor (they will have small knobs on them). Then use a flathead screwdriver to turn each one clockwise or counterclockwise until you achieve the desired result.
For example, if you want more power from your engine, you would turn all three screws clockwise slightly until you achieve desired performance without causing damage to your engine by over-revving it.It’s important to note that these adjustments should be made slowly and incrementally in order to avoid damaging your engine. Once you’ve found the perfect setting for your particular model of Stihl trimmer, be sure to write down those settings so that you can easily replicate them in future tune-ups!
Stihl Chainsaw Carburetor Adjustment Screws
If you’re a chainsaw user, then you know that a properly running carb is crucial to the saw’s performance. That’s why it’s important to understand the carburetor adjustment screws on your Stihl saw, what they do, and how to adjust them.There are three basic carburetor adjustment screws on most Stihl chainsaws: idle speed screw, low speed (or “L”) screw, and high speed (or “H”) screw.
The idle speed screw controls the engine’s idle RPMs, while the low and high speed screws control how much fuel is mixed with air at those respective speeds.Adjusting these screws can be a bit of a trial and error process, but there are some general guidelines you can follow. First, make sure the chain is not engaged and the throttle trigger is in the “off” position.
Then, start by adjusting the idle speed screw until the engine just begins to run without stalling. From there, you can begin adjusting the L & H screws according to how your saw is running at different speeds. If it’s running too lean (not enough fuel), turn both screws clockwise 1/8th of a turn; if it’s running too rich (too much fuel), turn both screws counter-clockwise 1/8th of a turn.
Keep making adjustments until the saw is running smoothly at all speeds with no stalls or hiccups.As always when working with power tools, use caution and consult your owner’s manual for specific instructions on your particular model of Stihl chainsaw before making any adjustments to your carburetor. With a little time and patience, though, you should be able to get your saw tuned up perfectly in no time!
How to Adjust a Chainsaw Carburetor from Scratch
If you’re a chainsaw user, then you know that a properly functioning carburetor is essential to the saw’s performance. A carburetor regulates the mixture of air and fuel that goes into the engine, and if it’s not adjusted properly, the saw will run inefficiently or not at all.There are two types of carburetors – adjustable and non-adjustable.
Adjustable carburetors can be fine-tuned to ensure optimal performance, while non-adjustable carburetors come preset from the factory and cannot be adjusted.If your chainsaw has an adjustable carburetor, there are four screws that control the different aspects of the air/fuel mixture – idle speed screw, low speed screw, high speed screw, and idle mixture screw. Each screw serves a specific purpose and adjusting just one without touching the others can result in poor performance.
The best way to adjust a chainsawcarburetor from scratch is to first identify which screws need to be adjusted. To do this, you’ll need a tachometer so you can check the engine’s RPMs while making adjustments. Once you’ve determined which screws need to be adjusted, turn them very slowly until you see an improvement in RPMs.
It’s important to go slowly because it’s easy to over-adjust and throw off the entire mixture. Continue making small adjustments until you reach peak RPMs – then back off slightly so the engine doesn’t rev too high and damage itself.
Stihl Carburetor Adjustment Tool
If you’re a chainsaw user, then you know that a properly running carburetor is key to the saw’s performance. The carburetor adjustment tool is an important part of keeping your Stihl saw in good running condition. This tool is used to adjust the mixture of air and fuel in the carburetor, and it’s critical to get the settings just right.
There are three screws on the side of most Stihl carburetors – one for idle speed, one for low speed (or “L”) mixture, and one for high speed (or “H”) mixture. Each screw has a different function, and they must be adjusted in the proper order or you risk damaging the engine.The first step is to warm up the engine by letting it run for a few minutes.
Then, turn off the engine and remove the spark plug so there’s no chance of accidentally starting it while you’re working on it. Next, use the adjustment tool to turn each screw clockwise until it lightly seated, and then back out each screw 1/2 turn.Now it’s time to start adjusting the screws.
Begin with the low speed mixture screw (“L”), and turn it slowly clockwise until the engine starts to run rough. Then back it out slightly until the engine runs smoothly again. Repeat this process with the high speed mixture screw (“H”).
Finally, adjustthe idle speed screw untilthe chainsaw idles smoothly without dying down too much when you rev it up briefly.Once all three screws have been properly adjusted, put everything back together and give your Stihl saw a test run! With a little bit of patience and care, you can keep your carburetor running like new – ensuring optimal performance from your chainsaw every time you use it!
How to Adjust High And Low on Carburetor
If your car is running too lean (a condition where there is not enough fuel in the mixture) or too rich (a condition where there is too much fuel in the mixture), you can adjust the high and low screws on the carburetor to compensate. The high screw adjusts the amount of fuel delivered when the engine is at wide-open throttle, while the low screw adjusts the amount of fuel delivered when idling.To adjust these screws, first locate them on the carburetor.
They are usually located near the bottom of the carburetor, and may have a cover over them. Once you have found them, use a flathead screwdriver to turn each one clockwise or counterclockwise until you achieve the desired result.If you are unsure about how to properly adjust your carburetor, consult a professional mechanic or take your car to a reputable service station.
Tuning a Chainsaw With a High And Low Setting
Chainsaws are one of the most versatile and powerful tools that you can have in your arsenal. But like any tool, they need to be properly maintained and tuned in order to function at their best. One of the most important aspects of chainsaw maintenance is setting the proper tension on the chain.
This is typically done by adjusting the high and low settings on the saw.If you’re not sure how to adjust the high and low settings on your chainsaw, don’t worry – it’s actually pretty simple. First, start by putting the saw on a level surface.
Then, locate the two screws that control the tension – one will be labeled “high” and the other “low”. To loosen the tension, simply turn each screw counterclockwise a few turns. To tighten the tension, turn each screw clockwise a few turns.
Once you’ve adjusted both screws to achieve the desired tension, make sure to test out your saw before using it for any major projects. The last thing you want is for your chain to come off while you’re in mid-cut!
Stihl 026 Carburetor Adjustment
If you’re having trouble with your Stihl 026 carburetor, it might need adjustment. Here’s a step-by-step guide on how to do it:1. Start by loosening the two screws that hold the carburetor in place.
2. Next, remove the air filter and unscrew the idle mixture screw until it’s flush with the housing.3. Now turn the high speed mixture screw clockwise until it stops, then back out 1 1/2 turns.4. Finally, replace the air filter and screw the carburetor back into place.
Conclusion
If your Stihl chainsaw is running too lean or too rich, you may need to adjust the carburetor. To do this, you’ll need to know how to read a spark plug. A lean mixture will cause the engine to run hot and may damage the engine.
A rich mixture will cause the engine to run cold and may cause the chainsaw to stall. Once you’ve determined which way to adjust the carburetor, turn the adjustment screw until the desired result is achieved.
