8 Common Stihl MS 271 Problems and Solutions
Stihl MS 271 is a popular chainsaw model known for its power and versatility. However, like all tools, it may experience some problems. Here are eight common issues and their solutions.
The engine Won’t Start
If your MS 271 engine won’t start, you should first check the fuel. Make sure the fuel cap is tight and that the fuel tank is full. If it’s a warm day, the fuel may have evaporated and you may need to add more.
Next, check the air filter. The air filter helps keep dirt and debris out of the engine, and if it’s dirty, it can keep the engine from starting. If the air filter is dirty, replace it with a new one.
Finally, make sure the spark plug is clean and has a good spark. If it doesn’t, replace it with a new one.
There are several reasons why your MS 271 engine might stall. One of the most common reasons is when the chain becomes too tight. If the chain is too tight, it can make the engine stall.
Another reason the engine might stall is if there is a fuel mix issue. If there is not enough oil in the fuel mix, it can cause the engine to stall. You can prevent this by making sure you are using the correct fuel mix for your MS 271 and by keeping the air filter clean.
To fix this issue, the spark plug should be removed, cleaned, and replaced. A clogged or dirty fuel filter can also cause the engine to stall. This can occur if the fuel filter becomes clogged with dirt or debris, preventing the proper fuel flow to the engine. To fix this issue, the fuel filter should be removed, cleaned, and replaced.
Finally, a dirty or clogged carburetor can also cause the engine to stall. This can occur due to debris blocking the fuel or airflow to the engine. To fix this issue, the carburetor should be removed, cleaned, and reassembled.
If you are experiencing engine stalling issues with your Stihl MS 271 chainsaw, these solutions may help resolve the issue. If the issue persists, however, you should contact an authorized Stihl service center for further assistance.
Chain Doesn’t Move
If your chain doesn’t seem to be moving when you pull the starter cord, there are a few things you can check.
First, make sure the chain catcher is engaged by pushing it down with your thumb. If it’s properly in place, check the chain tension. It should be snug but not too tight.
You can also try adjusting the carburetor a bit to get the engine running a little richer. If all of that fails, it might be time to bring in your MS 271 for a tune-up.
Bar Won’t Turn
If your Stihl MS 271’s bar won’t turn, the possibility of it being a jammed chain may be the most likely cause. To check if this is indeed the issue, you can take off the chain and inspect it for any blockages or obstructions. If there is any damage to the bar or if the sprocket doesn’t spin at all, then these are signs that you’ll need to replace them.
Also, make sure that your chain brake is disengaged when you’re trying to start up your chainsaw. If it’s engaged when you try to turn the Stihl MS 271 on, then this will keep the bar from moving.
Remember that lubricating your chainsaw is important for the optimal performance of all its components. If everything looks okay after inspecting and troubleshooting your chainsaw, but it still won’t turn, then check to see if there’s enough oil in the system before calling a technician for help.
Engine Runs Poorly
The poor engine is a very common issue with Stihl MS 271. There are a few things you can check. The spark plug might be old or dirty and need to be replaced. You’ll also want to check the fuel lines and filter, as these can clog up if they’re not regularly serviced. Another common issue is an air leak, which you can usually identify by checking the air filter or air cleaner.
You should also check the fuel-to-air ratio. This is usually a problem when the engine has been running on old fuel for too long, so topping off with fresh fuel will likely do the trick. Finally, it’s possible that the carburetor is out of adjustment and needs to be adjusted by a professional technician for optimal performance.
Chain Comes Off
The chain may come off when you operate the chainsaw, which can be a safety hazard. This usually happens if the chain has become loose, so you’ll need to make sure it’s tightened down properly. You may need to re-fasten the nuts and bolts if you can’t get them tight enough with just your hands.
To fix this issue, put on a pair of gloves and take off the side panel of the chainsaw. Once it’s removed, apply some light pressure with your thumb over the sprocket when tightening down the nuts and bolts. This will stretch out the chain so that it’s snug when everything is fastened up again.
Another important thing to check is that the bar is inserted correctly into position—if it’s not, then no matter how tight you get the nuts and bolts, they won’t hold when you start cutting wood. Be sure that everything is in its rightful place before use.
If you’re noticing any kind of oil leak with your Stihl MS 271, there are a few things you can try. First, check the seals and make sure they are in good condition. If not, it’s time to replace them. Additionally, make sure that the air filter is in good condition and free of debris. If the filter is in bad shape, it’s possible that oil could be leaking out through it.
Finally, if your bar nuts are loose, this could be causing an oil leak. Make sure these nuts are securely tightened so they won’t come loose and cause an issue. If all else fails, you may need to replace the bar itself or seek professional assistance from a qualified technician to identify any other potential issues with your saw.
Are you experiencing excessive vibration when using your Stihl MS 271 chain saw? If so, there are a few things you can check to find the source of the problem.
First, make sure that the chain is properly tensioned. If the chain tension is too loose or too tight, it can cause excessive vibration and decrease the life of your chain. Also, check that the bar and guide bar screws are properly tightened and that the guide bar retaining bolt is also secure.
If these solutions don’t resolve your issue, you should consider replacing your saw’s parts such as the spark plug, air filter, and fuel filter. Make sure to use genuine Stihl replacement parts for these components as cheap knockoffs might not fit properly or work as well.
Also, if you have a damaged or worn-out cylinder or piston, it might be time for an overhaul – something best left to a professional chainsaw technician.
How to Replace the Air Filter in a Stihl MS 271
First, make sure the chainsaw is turned off and unplugged. Next, remove the spark plug cap and using a socket wrench, loosen the two nuts that hold the air filter housing in place. Swing the housing out and remove the filter.
Replace the old filter with a new one, making sure that it’s inserted correctly and reattach the air filter housing. Tighten the two nuts securely. Replace the spark plug cap and start up your chainsaw.
When to Replace the Spark Plug on a Stihl MS 271?
The MS 271 has a spark plug that should be replaced every season. This is to ensure that the saw runs smoothly and doesn’t have any problems. If you don’t replace the spark plug, you might end up with a saw that is hard to start or one that cuts poorly.
How to Troubleshoot Ignition Issues in a Stihl MS 271?
If you’re experiencing ignition issues with your Stihl MS 271, don’t worry—you’re not alone. These problems are actually quite common, and can often be fixed with a bit of troubleshooting.
The first thing you should do is check the spark plug. A dirty or corroded spark plug can often be the source of ignition problems. If the spark plug is dirty, clean it off with a wire brush and some denatured alcohol. If it’s corroded, you’ll need to replace it.
You should also check the air filter. A dirty air filter can also cause ignition problems. If the air filter is dirty, replace it with a new one.
If you’ve checked the spark plug and the air filter and you’re still experiencing problems, there may be something wrong with the carburetor. In this case, you’ll need to take your saw to a qualified technician for repair.
