It is possible that your Stihl chainsaw is dying when you give it gas if the carburetor, spark plug, chain, or air filter is malfunctioning. If the carburetor is clogged or not adjusted properly, it can cause the saw to run out of fuel.
If the spark plug is fouled, it means that it is unable to ignite the fuel being provided to the cylinder. If the chain is loose or dull it may result in the saw not having enough power to keep running.
Lastly, if the air filter is dirty or clogged it will restrict the air flow and cause the saw to lose power.
If you have recently bought the saw or it has been sitting for a while and not used, the best option would be to clean the carburetor and set it according to the factory specs. Additionally, it is a good idea to check the spark plug to make sure it is in good condition.
You should also check the chain tension and sharpness and consider replacing the chain if that is necessary. Lastly, you should clean the air filter and replace it if necessary. That should help improve the performance of the chainsaw and resolve the issue of your saw stalling when you give it gas.
How do you fix a chainsaw that won’t stay running?
If your chainsaw won’t stay running, there are several steps you can take to try and fix it before seeking professional help. The first step is to make sure that your chainsaw has enough fuel. Check the fuel tank for the correct fuel and oil mixture, filling it up if necessary.
Next, check the spark plug to make sure it is clean and properly connected. If the spark plug is cracked or damaged, you will need to replace it. If the plug checks out, try removing it and spraying it with aerosol-based cleaner.
This may solve the problem.
Next, you should check the air filter to make sure it is clean and not blocked by dirt or debris. If it needs to be cleaned, take care to not damage it by using compressed air or a soft brush. Additionally, inspect the air vents on the engine to make sure they are not blocked by leaves or debris.
Finally, check the choke. Make sure it is moveable and not stuck in the open or closed position. If it is stuck, try loosening the nut to free it up. If these steps do not solve the problem, you should take the chainsaw to a professional for servicing or further diagnosis.
How do you clean a carburetor on a chainsaw without removing it?
Cleaning a carburetor on a chainsaw without removing it can be done with a few simple steps. First, disconnect the spark plug wire and turn the engine off. Then, remove the air filter and fuel filter.
Clean both of these components if they are dirty. Next, spray a carburetor cleaner into the throat of the carburetor on the side opposite the air filter and throttle linkage. Rotate the fuel supply lever and keep it in the “on” position while you spray the carburetor cleaner.
Allow the cleaner to sit for five to 10 minutes and then wipe away with a cloth. Finally, replace the fuel filter and air filter and reconnect the spark plug. Start the chainsaw for a few seconds to make sure the carburetor is functioning correctly.
How do you unclog a chainsaw carburetor?
To unclog a chainsaw carburetor, you’ll need to thoroughly clean the carburetor and replace the air filter. First, be sure to read your chainsaw’s manual to determine whether you need specialized tools to disassemble the carburetor.
If needed, purchase the tools from a hardware store and make sure you have personal protective equipment (goggles, gloves, etc. ) before starting the process.
Begin by draining the fuel tank and draining the existing fuel from the carburetor. In order to properly access the carburetor and get at its internal components, you’ll then need to disassemble the carburetor.
Take great care in removing the smaller parts and remove any debris or build up in the carburetor. While you are in there, check the spark arrestor screen to make sure it is clear and that there is not any debris clogging it.
Using compressed air, blow out the inside of the carburetor and around the gasket. Also, use a clean cloth and some carburetor cleaner to wipe down the inside of the carburetor. To ensure any residue is removed, spray the inside of the carburetor with carburetor cleaner and scrub with a stiff brush.
After reassembling the carburetor make sure the gaskets and seals are airtight.
Finally, replace the air filter on the chainsaw. Your manual will provide detailed instructions on how to do this. Once you’ve reassembled the chainsaw and replaced the air filter, check for any other issues, like clogged fuel cap vent, and make sure all the screws have been secured correctly.
Once complete, start the engine and check to make sure the chainsaw is now running correctly.
Why does my chainsaw start and then stop?
Chainsaws can start and then stop for a variety of reasons, so it’s important to take the time to diagnose the problem before attempting to start it again. First and foremost, you should check that you are using the correct fuel and oil mixture for your chainsaw.
If the fuel you are using is too old or is diluted, your chainsaw will not work correctly. You should also check the spark plug and air filter to make sure that they are not clogged or damaged. A clogged air filter or spark plug can cause your chainsaw to start and then stop.
Furthermore, it’s possible that the carburetor is not getting the right amount of fuel, so it’s important to check the fuel lines and adjust the carburetor accordingly. Additionally, the choke might be stuck in either the open or closed position and preventing the engine from running properly.
Finally, the ignition system might need to be adjusted or repaired, and for this, you should contact a professional for assistance. Taking all of these potential issues into account and fixing them as needed should help to correct the issue and get your chainsaw running properly.
Why does my Stihl saw keep stopping?
If your Stihl saw keeps stopping, there could be several potential causes. The most common causes of a Stihl saw stalling out or stopping include clogged air filter, fouled spark plug, stale gasoline, low compression in the cylinder, insufficient fuel reaching the carburetor, blocked fuel lines, incorrect gap between the spark plug electrodes, a worn or broken drive belt, and inadequate lubrication of the saw chain.
To rule out any of these as a potential cause, it’s important to first check the air filter. If it’s clogged, replace it with a clean one. If the air filter is clean, then the spark plug should be cleaned and gap adjusted to the manufacturer’s specifications.
If the spark plug is physically damaged, replace it. If the spark plug looks good, check the fuel mix. If the fuel mix is old or has not been adjusted properly to the manufacturer’s specifications, refresh it or adjust it.
If the fuel lines are blocked or restricted, clean or replace them accordingly. If the drive belt is worn or broken, replace it with a new one as soon as possible. Make sure to properly lubricate your chain with chain oil and check the compression in the cylinder.
If the compression is low, you should clean and check for any damage or wear.
By properly troubleshooting and addressing any potential causes, you can prevent stalling or restarting problems with your Stihl saw.
How do you adjust the carburetor on a Craftsman chainsaw?
Adjusting the carburetor on a Craftsman chainsaw is a relatively simple process, but there are several steps you’ll need to follow. Before you start, be sure to read the manufacturer’s instructions carefully.
1. Start by identifying the carburetor on your saw. Most Craftsman models have either a standard Walbro or a Zama carburetor. You may have to look beneath the air filter or in the Users Manual for your saw’s model number.
2. Unscrew the carburetor cover and expose the main jet. This jet is usually responsible for controlling the fuel/air mixture.
3. Adjust the idle speed. You’ll want to start by increasing the idle speed until the engine runs smoothly. This can usually be done by turning the adjustment screw clockwise.
4. Adjust the main jet by twisting the needle in either direction. Turning it clockwise will increase fuel flow, and turning it counterclockwise will reduce fuel flow.
5. Adjust the air screw until the idle speed is consistent. This is done by turning the air screw in either direction, depending on the engine’s response.
6. Re-attach the carburetor cover and test the saw. Run the saw in idle and make sure the idle speed is consistent, and then rev it up and listen for any unexpected changes in engine noise.
Once you’ve made the adjustments, make sure to monitor the performance of your saw over the next few days and readjust if necessary.
What is the T adjustment on chainsaw?
The T adjustment on a chainsaw is a tool-free tensioning system that makes it easier for users to adjust the tension of the chain. This feature is commonly found on modern chainsaws, and is designed to make adjusting the chain tension quick and easy.
To adjust the tension on the chain, the user simply turns a knob located near the drive sprocket. Turning the knob will either tighten or loosen the chain, depending on the direction the user turns the knob.
Proper adjustment is critical for safe operation and efficient cutting performance, and the T adjustment allows anyone to determine the accurate tension of their chainsaw chain in a matter of seconds.
What causes a chainsaw to bog down when accelerating?
When a chainsaw bogs down when accelerating, it typically means the engine is not receiving enough fuel or air. The engine needs a precise mixture of air and fuel to run efficiently, and when the ratio is off, it can bog down.
For example, if the carburetor is clogged, not tuned correctly, or is contaminated, it may not be metering the right amount of fuel. Additionally, if the air filter is dirty or blocked, that can also lead to a bogging issue.
Other potential causes of bogging may include a spark plug that needs replacing, fuel that has gone bad, incorrect fuel-oil mixture, chain that is too tight, or even an over-revved engine.
Where is the fuel filter on a Poulan chainsaw?
The location of the fuel filter on a Poulan chainsaw varies depending on the model. Generally, you will find the fuel filter on the fuel line, usually near the carburetor. On most models it is either just below or just above the carburetor and secured with a metal clip.
To remove it you need to depress a small tab and slide the fuel line off. It is recommended to replace the fuel filter every year to ensure optimal performance and avoid any possible issues. Be sure to check your model’s owner’s manual for the exact location of the fuel filter as it can vary from model to model.
