A chainsaw not idling within normal parameters can have several contributing factors. This can include the following:
1. Clogged air filter: A clogged air filter reduces the amount of air being delivered to the carburetor, meaning there is less air to mix with fuel, and thus the saw is unable to reach the correct idle.
2. Dirty spark plug: The spark plug needs to fire to ignite the fuel/air mixture in the combustion chamber for the engine to idle at the correct speed. A spark plug that has become fouled due to a build-up of dirt and grime will not fire properly, reducing the engine to idle.
3. Fuel filter clogged: The fuel filter is responsible for preventing contaminants from reaching the carburetor. A clog or build-up of dirt and grime on the filter will reduce the amount of fuel getting to the carburetor, resulting in insufficient fuel/air mixture to allow the engine to idle.
4. Throttle adjustments: On some chainsaws, the throttle can be adjusted to control the engine speed. If the throttle is adjusted incorrectly, the engine will be unable to reach a normal idle.
5. Worn carburetor: If the carburetor has become worn or damaged due to wear and tear, it can cause issues with the fuel/air mixture being delivered to the combustion chamber. This will reduce the amount of power being transferred from the fuel to the engine, causing the engine to not idle correctly.
The best way to diagnose the cause for a chainsaw not idling correctly is to check for any of the above mentioned issues. Once the issue is determined, the corresponding part can be replaced or adjusted to bring the chainsaw back to its proper functioning state.
Why does my chainsaw start but not stay running?
The most common cause of a chainsaw that starts but won’t stay running is a problem with the fuel or air filter. If your chainsaw has clogged fuel or air filters, it may start but not run for long due to an inability to draw in enough fuel or air to maintain the engine’s RPMs.
Additionally, spark plugs that are old or improperly gapped can malfunction, resulting in a chainsaw that starts but won’t stay running. Finally, if the chain itself is too tight or the chain brake is activated, this can prevent the engine from maintaining its RPMs, and again, cause it to start but not stay running.
Checking for these and other potential causes can usually get your chainsaw up and running.
How do I fix the idle on my chainsaw?
To fix the idle on your chainsaw, the first thing you should do is check the air filter. If it is dirty or clogged, replace it. If it is still in good condition, try cleaning it with a compressed air canister.
Next, check the spark plug to make sure it is tight and not fouled. If it needs to be replaced, use a spark plug with the correct gap for your saw. Make sure the spark plug is clean and dry before installing.
Next, check the fuel lines for any clogs or cracks. If you find any, replace the lines with the correct parts. Make sure to properly secure the fuel lines with the correct clamps.
Then, adjust the idle settings for the chainsaw. The idle settings can usually be found and adjusted on the carburetor. Make sure to refer to the manufacturer’s specifications for the correct idle settings.
Finally, if all of the above steps don’t fix the idle, it may be necessary to rebuild or replace the carburetor. This should be done by a professional if you are not familiar with the process.

You can purchase these products at most hardware stores, home improvement stores, or online. Before using any new product on your chainsaw, make sure to read the directions and follow all safety warnings closely.
Can I use starting fluid on a chainsaw?
No, you should not use starting fluid on a chainsaw. Starting fluid is highly flammable, and when sprayed close to the spark plug of a chainsaw it could ignite, causing a fire or other serious damage.
Instead of using starting fluid, you should focus on ensuring your chainsaw has enough fuel, the air filter is not clogged, and the spark plug is in good condition. Check the user’s manual to make sure you understand how to properly start and maintain the chainsaw.
Also, verify that the spark plug has a good spark. If it does not, replace it with one that does. Additionally, make sure that your chainsaw is properly lubricated and that the chain tension is properly adjusted.
Finally, ensure that the choke is in the appropriate position when starting the chainsaw. Following these steps should result in a successful and safe start.
How do you start a Stihl chainsaw without flooding?
Starting a Stihl chainsaw without flooding it can involve three steps:
1. Preparation: Start by making sure the saw’s fuel tank is full of fresh fuel, that the spark plug gap is correct, and that the air filter is clean.
2. Priming: Lift the saw up so that the fuel tank is at least half full and press the priming bulb three to four times. This will pump fuel into the cylinder and make starting easier.
3. Starting: Pull the starter cord a few times in quick succession to get the engine running. Make sure to not pull the cord too far in order to minimize flooding.
By following these steps, it should be fairly simple to start a Stihl chainsaw without flooding it.
Why does my chainsaw dies when I give it gas?
One possibility is that your chainsaw is running on too little fuel. If the fuel mixture is too lean, the engine can run until there is no fuel left, resulting in it dying as soon as you give it gas.
To fix this problem, you should make sure that your fuel mixture is correct and that you’re using the appropriate amount of fuel.
Another possibility is that your chainsaw isn’t getting enough air. If there’s something blocking the air intake, then it won’t be able to draw in enough air for the engine to work properly. To fix this, you should check to make sure there isn’t anything obstructing the air intake and that the air filter is clean.
It’s also possible that something is wrong with your spark plug or ignition system. If the spark plug is worn out or the ignition system isn’t working properly, then the engine won’t be able to start even when fuel and air are available.
To fix this, you should check the spark plug and the other components of the ignition system and replace any parts that aren’t in good condition.
Finally, it’s possible that something else is wrong with your chainsaw. If none of the above steps have solved the issue, then you should take it to a qualified mechanic so they can inspect it and identify the underlying problem.
Why does my chainsaw cut off when I pull the trigger?
There are a variety of reasons why your chainsaw might be cutting off when you pull the trigger. It could be an issue with the spark plug, fuel lines, air filter, or carburetor. It could also be a problem with the engine, such as a blocked cylinder, seized piston, or dirty spark arrestor.
It could also be that your chainsaw has an ignition switch that is faulty or not properly adjusted. Before you attempt to repair the issue yourself, you should identify the exact problem by inspecting the engine and fuel supply components.
If the problem persists after inspection, it may be best to contact a professional or take your chainsaw into a repair shop.
How do you adjust H and L screws on a carburetor?
To adjust the high and low screws on a carburetor, begin by inspecting the carburetor and jets to ensure that they are undamaged and operating properly. Once you’ve determined that the carburetor is in good condition, the next step is to warm up the engine so that it runs smoothly.
This will help you set the high and low screws in the proper position.
Now, start by locating the two adjustment screws on the side of the carburetor: the “H” screw, which stands for “high,” and the “L” screw, which stands for “low. ” The “H” screw controls the fuel/air ratio at higher speeds and the “L” screw controls the fuel/air ratio at lower speeds.
Using a screwdriver, turn the “H” screw clockwise until you hear the engine’s RPM increase. Then, turn the “L” screw clockwise until the engine’s RPM decreases. Repeat this cycle an additional time to ensure proper adjustments.
Keep adjusting until the engine runs smoothly, with no “bogging” or “hesitation. “.
At this point, it’s also important to adjust the idle screw to keep the engine running at a steady speed. Once the idle screw is adjusted, you can move the “H” and “L” adjustment screws in opposite directions to fine-tune the fuel/air ratio and ensure smooth performance.
Once the H and L screws are adjusted, it’s essential to monitor the engine’s performance and adjust as needed to maintain optimal performance. Remember to always use safety precautions when adjusting the carburetor and never attempt to adjust the carburetor while the engine is running.
What does H and L mean on Stihl chainsaw?
H and L are two of the designations used for chainsaw chain pitch, which is the size of the chain that you can run on a specific saw. The H designation is for 3/8 inch pitch and the L designation is for.
325 inch pitch. These two chain sizes are the most common pitch sizes used on Stihl chainsaws, with the Stihl MS 291 having the ability to run either a 3/8 inch or a. 325 inch pitch chain. The size of the chain that you choose should match the size that is specified in your operator’s manual.
It is important to select a proper-sized chain, as an incorrectly-sized chain can cause serious damage to your saw by increasing the likelihood of kickback, increasing wear on the guide bar and sprocket, and reducing the cutting power of your saw.
How do you adjust air fuel mixture screws?
Adjusting air fuel mixture screws requires a few steps:
1. Start by identifying the screws on the carburetor – they’re typically located near the base of the carburetor.
2. Adjust the screws in half-turn increments. Start with the passenger side screw first and work your way around to the driver side.
3. Increase the turns on one side while decreasing the turns on the other to ensure an even mixture of air and fuel. This will help avoid imbalances that could cause the engine to run rich or lean.
4. After each turn, have someone start the engine and let it idle for several seconds. Pay attention to the sound and performance of the engine.
5. If the engine is running smoothly and evenly, turn the screws slightly until it begins to stutter or run rough.
6. When the engine runs rough, slowly turn the screws back until it runs consistently and evenly again.
7. Once the engine is running smoothly and evenly, it is important to check the air/fuel mixture with a CO2 tester. Doing this will ensure that the air/fuel mixture is within the manufacturer’s specifications.
8. Repeat these steps on the other side of the carburetor.
9. Finally, it is also a good idea to check your spark plugs after each adjustment– if they are too light or dark in color, it might indicate that you need to adjust the air/fuel mixture screws again.
