How to Adjust Carburetor on a Chainsaw

The carburetor on a chainsaw controls the amount of fuel and air that is delivered to the engine. The carburetor may need to be adjusted if the chainsaw is not running properly. To adjust the carburetor, first unscrew the cap on the back of the chainsaw.

Then, turn the adjustment screws until the chainsaw runs smoothly.

  • Check the saw’s air filter to ensure it is clean
  • A dirty air filter will restrict air flow to the carburetor, causing the engine to run lean
  • Remove the spark plug and inspect it
  • If the electrode is burnt or damaged, replace the plug
  • Locate the screws on the side of the carburetor that adjust idle speed and mixture control
  • Turn both screws clockwise until they are snug against the stop limiter without going too far past it
  • This will set a baseline for further adjustments
  • Start up the chainsaw and let it idle for a few minutes so you can make sure all parts are working correctly before cutting wood with it
How to Adjust Carburetor on a Chainsaw


How Do You Adjust a Carburetor That is Running Rich?

A carburetor that is running rich means that it is adding too much fuel to the engine. This can happen for a number of reasons, such as a dirty air filter or an incorrect carburetor setting.If you think your carburetor is running rich, the first thing you should do is check the air filter.

If it’s dirty, clean it and see if that makes a difference. If not, then you’ll need to adjust the carburetor itself.To adjust a carburetor that is running rich, you’ll first need to identify which screw controls the fuel mixture.

This will usually be located on the side of the carburetor body. Once you’ve found it, turn it clockwise until the engine starts to run leaner (less fuel). Keep adjusting until the engine is running smoothly and at its best performance.

What is the L And H on Chainsaw?

If you’re a homeowner, there’s a good chance you’ve seen the letters “L” and “H” on your chainsaw. These letters refer to the saw’s guide bar length and engine size, respectively. The guide bar is the part of the saw that holds the chain, and its length is measured from tip to tip.

The engine size, meanwhile, is measured in cubic centimeters (cc).Generally speaking, a longer guide bar will allow you to make longer cuts, while a larger engine will give you more power. That said, there are trade-offs to consider.

A longer guide bar may make the saw more difficult to handle, and a larger engine may make the saw heavier and more difficult to control. Ultimately, it’s up to you to decide which combination of features best suits your needs.

How Do You Adjust a 2 Cycle Carburetor?

If your 2-cycle engine is having trouble starting up, or is running erratically, it may be time to adjust the carburetor. This process is relatively simple, and can be done with a few tools that you likely already have on hand.First, locate the carburetor on your engine.

It will be attached to the intake manifold, and will have a fuel line running into it. There will also be a throttle cable attached to the carburetor. Once you’ve found the carburetor, you’ll need to remove the air filter housing so that you can access the adjustment screws.

There are two adjustment screws on most 2-cycle carburetors: L and H. L is for low speed mixture adjustment, while H is for high speed mixture adjustment. To begin adjusting the carburetor, turn both screws clockwise until they’re fully closed. Then, open the L screw one full turn counterclockwise.

Next, start up your engine and let it idle for a minute or so. If it’s still running erratically, turn the L screw another 1/8 of a turn counterclockwise and let it idle again. Repeat this process until the engine is idling smoothly.

Once you’ve got the engine idling smoothly at low speeds, it’s time to adjust the H screw. Open up this screw 1/2 of a turn counterclockwise from where it was originally set (i.e., if it was turned all the way clockwise before, now turn it 1/2 of a turn counterclockwise). Let the engine run for a minute or two at higher speeds; if necessary, fine-tune by opening or closing this screw until things sound good at higher RPMs as well.

And that’s all there is to adjusting a 2-cycle carburetor!

Why Does My Poulan Chainsaw Dies When I Give It Gas?

If your Poulan chainsaw dies when you give it gas, the most likely culprit is a problem with the carburetor. The carburetor mixes air and fuel in the correct ratio to allow the engine to run, and if it isn’t working properly, the engine will stall. There are several things that can cause carburetor problems, including a dirty air filter or spark plug, old or stale fuel, or a clogged fuel line.

One of the first things to check if your chainsaw stalls when you give it gas is the air filter. If it’s dirty, it can restrict airflow to the engine and cause it to stall. Clean or replace the air filter as needed.

You should also check the spark plug; if it’s fouled or damaged, it could be causing misfires that lead to stalling. Finally, make sure there’s fresh fuel in the tank and that the fuel line isn’t clogged. If all else fails, take your chainsaw to a qualified technician for service.

How to Adjust High And Low on Carburetor

If you’re having trouble with your carburetor, one of the first things you should check is the high and low settings. These two screws control the amount of air and fuel that enters the engine, and adjusting them can often fix common problems. Here’s a step-by-step guide to adjusting the high and low on your carburetor.

1. Locate the screws. On most carburetors, these will be located near the bottom of the unit. They are usually labeled “H” for high and “L” for low.

2. Adjust the screws slightly. Turn both screws a quarter turn in the same direction (either clockwise or counterclockwise). This will make a small adjustment to the mixture of air and fuel entering the engine.

3 .Start the engine and let it idle . If the engine stalls or runs roughly, try turning both screws another quarter turn in either direction until it runs smoothly .

Alternatively , if one screw needs to be adjusted more than the other , do so until both sides are balanced out . Sometimes it takes a few tries to get it just right, so don’t be discouraged if it doesn’t work perfectly on your first try!

What is the T Adjustment on Chainsaw

Chainsaws are one of the most versatile and useful tools that a homeowner or professional can have. They come in handy for a variety of tasks, from cutting down trees to trimming branches and even cutting firewood. But like any tool, they need to be used correctly in order to work properly and safely.

That’s where the T adjustment on chainsaws comes in.The T adjustment is the tensioner that sets the amount of slack in the chain. It’s located at the base of the saw near the handle, and it’s usually marked with a “T” or an arrow.

To adjust the tension, simply turn the knob clockwise to tighten or counterclockwise to loosen. It’s important to keep the chain tight, but not too tight, as this can damage both the saw andthe chain. If you’re not sure how tight to set it, consult your saw’s manual for guidance.

Once you’ve got the hang of using your chainsaw, you’ll wonder how you ever managed without one!

Chainsaw Won’T Start Carb Adjustment

If your chainsaw won’t start, it could be due to a number of issues. One possibility is that the carburetor needs adjustment. This is a relatively easy fix that you can do yourself, but it’s important to know how to adjust the carburetor properly.

The first step is to identify which screws need to be adjusted. There are typically two screws: the idle adjustment screw and the high-speed adjustment screw. The idle adjustment screw controls the engine speed when the chainsaw is idling, while the high-speed adjustment screw controls the engine speed when the throttle is fully open.

Once you’ve identified which screws need to be adjusted, you’ll need to use a wrench or screwdriver to turn them. To adjust the idle speed, turn the idle adjustment screw clockwise until the engine speeds up. Then, turn it counterclockwise until the engine slows down again.

Find the sweet spot in between these two settings so that the engine runs smoothly at low speeds.To adjust the high-speed setting, turn the high-speed adjustment screw clockwise untilthe engine speeds up, then back off slightly until it runs smoothly at full throttle. Again, findthe sweet spot in between these two settings for optimal performance.

After making your adjustments, test out your chainsaw to see if it’s running better now.

Stihl Chainsaw Carburetor Adjustment Screws

If your Stihl chainsaw is running too lean or too rich, you may need to adjust the carburetor. The carburetor adjustment screws are located on the side of the carburetor and are used to fine tune the engine. The “L” screw is for low speed (idle) and the “H” screw is for high speed.

To adjust the low speed screw, turn it clockwise to lean out the mixture or counterclockwise to richen it. To adjust the high speed screw, turn it clockwise to richen the mixture or counterclockwise to lean it out. Be careful not to over-adjust either screw as this can damage the engine.

Tuning a Chainsaw With a High And Low Setting

If you’re like most people, you probably don’t think too much about the different settings on your chainsaw. But if you want to get the most out of your saw, it’s important to understand how to adjust the high and low settings. Here’s a quick guide to help you get started.

The first thing you need to do is find the adjustment screws on your saw. These are usually located near the front of the saw near the bar. Once you’ve found them, take a look at the chain and make sure it’s properly tensioned.

If it’s not, use the adjustment screws to loosen or tighten the chain until it’s tight enough that there shouldn’t be any slack when you pull on it.Next, start your saw and let it warm up for a few minutes. Then, slowly increase the throttle until the chain is spinning at full speed.

At this point, you can begin adjusting the high setting screw. Turning it clockwise will increase the speed of the chain, while turning it counterclockwise will decrease the speed. Play around with this until you find a setting that works well for whatever task you’re working on.

Once you’ve got the hang of things, try adjusting the low setting screw as well. This one works in pretty much exactly opposite way as high setting screw – turning it clockwise will decrease speed while turning counterclockwise will increase speed . Again , play around until find a comfortable setting .

One final tip: if your saw starts smoking excessively or making strange noises , back off on throttle immediately ! These could be signs that something is seriously wrong and continuing use could damage both your saw and yourself .

Chinese Chainsaw Carburetor Adjustment

If you have a Chinese chainsaw, you may need to adjust the carburetor from time to time. This is a simple process that only takes a few minutes. Here’s how to do it:

1. Locate the carburetor adjustment screws. These are usually located on the side of the carburetor body.2. Turn the “L” screw clockwise until it is tight.

This is the low speed adjustment screw.3. Turn the “H” screw counterclockwise until it is tight. This is the high speed adjustment screw.

4. Start the chainsaw and let it idle for a few minutes. If it seems like the engine is running too fast, turn the “L” screw counterclockwise until it slows down to an acceptable level. Likewise, if the engine seems to be running too slow, turn the “H” screw clockwise until it speeds up slightly.

Chainsaw Tuning

If your chainsaw isn’t running as smoothly as it should be, it might be time for a tune-up. Chainsaws need regular maintenance to keep them running properly, and tuning is an important part of that.There are a few things you’ll need to do when tuning your chainsaw.

First, check the chain tension and adjust it if necessary. The chain should be tight enough that it doesn’t sag, but not so tight that it’s difficult to move.Next, clean the air filter and spark plug.

A dirty air filter can restrict airflow and cause the engine to run poorly. A dirty spark plug can also cause problems.Once those things are taken care of, you’ll want to adjust the carburetor.

This is where things can get a bit tricky, so it’s best to consult your chainsaw’s manual or take it to a professional if you’re unsure how to do this.With all of that done, your chainsaw should be running better than ever! Regular tune-ups will keep it in good condition and help prevent future problems.


If your chainsaw is having trouble starting, it might be time to adjust the carburetor. This is a relatively simple process, and only takes a few minutes. First, make sure the chainsaw is turned off and cooled down.

Then, remove the air filter cover and unscrew the two screws that hold the carburetor in place. Next, use a flathead screwdriver to turn the idle mixture screw clockwise until it stops. Finally, replace the air filter cover and start the chainsaw to test it out.
