The most common issues with Poulan Pro 42cc chainsaws are related to the chain not moving, the engine not starting, or the saw being difficult to operate. If the chain is not moving, it could be because the chain is too tight. To fix this, loosen the tensioner knob and turn the chainsaw over so that the bar is facing up.
Then, pull the chain around the bar until it is loose enough to move freely. If the engine is not starting, it could be due to a number of issues, such as old gasoline, a dirty air filter, or a faulty spark plug. To troubleshoot this issue, start by checking these three things and making sure they are all clean and free of debris.
Finally, if the saw is difficult to operate, it could be due to a dull blade or an incorrect blade size. Be sure to check both of these things before using your saw again.
If your Poulan Pro 42cc chainsaw isn’t working properly, there are a few things you can do to troubleshoot the problem. First, check the spark plug to make sure it’s clean and in good condition. Next, check the air filter to see if it needs to be replaced.
If neither of these solutions solves the problem, you may need to take your chainsaw to a professional for further diagnosis and repair.

Why Does My Poulan Chainsaw Die When I Give It Gas?
If you’re experiencing problems with your Poulan chainsaw dying when you give it gas, there are a few potential issues that could be the culprit. First, check the saw’s spark plug to make sure it is clean and in good condition. If the spark plug is fouled or damaged, it could cause the engine to misfire and die.
Next, check the air filter to make sure it is clean and not restricted. A dirty or restricted air filter can cause an engine to run lean and stall. Finally, check the fuel mixture in the saw’s gas tank.
The proper fuel mixture for a Poulan chainsaw is 50:1 (gasoline: oil). If the mixture in the tank is too rich or too lean, it could cause stalling issues.
Why Will My Poulan Pro Chainsaw Not Start?

There are a number of reasons why your Poulan Pro chainsaw might not be starting. The most common reason is that the spark plug isn’t firing. This can be caused by a number of things, including a dirty spark plug, a loose connection, or a faulty ignition coil.
Another possibility is that the carburetor is flooded, which can happen if you try to start the saw when it’s too cold outside. Finally, make sure that there’s enough fuel in the tank – if it’s empty, the saw won’t start!
Why Does My Chainsaw Start But Won’t Stay Running?
If your chainsaw starts but won’t stay running, there are a few possible explanations. First, the saw may be flooded with fuel. To fix this, remove the spark plug and insert a small wire into the hole.
Turn over the engine a few times to clear out the fuel, then try starting it again. If this doesn’t work, the problem may be with the carburetor. Adjusting the carburetor can be tricky, so it’s best to consult a professional if you think this is the issue.
Finally, make sure that your saw has enough oil. If it doesn’t have enough oil, it will overheat and shut down. Add more oil if needed, and then try starting your chainsaw again.
How Do You Adjust the Carburetor on a Poulan Chainsaw?

If your Poulan chainsaw is running too lean or too rich, you may need to adjust the carburetor. Running too lean means that not enough fuel is being mixed with the air while running too rich means there’s too much fuel and not enough air. Both of these scenarios can lead to engine damage over time, so it’s important to make sure your carburetor is adjusted properly.
There are two screws on the side of the carburetor that control the fuel mixture – one for idle and one for high speed. To adjust the carburetor, first identify which screw needs to be turned. If your chainsaw is running lean (not enough fuel), turn the screw labeled “H” counterclockwise by 1/8 turn.
If it’s running rich (too much fuel), turn the “L” screw clockwise by 1/8 turn. Once you’ve made an adjustment, start up the chainsaw and let it run for a few minutes to see how it responds. If it’s still not running correctly, repeat the process until it’s tuned properly.

Poulan Chainsaw Carburetor Adjustment
If your Poulan chainsaw starts to act up, one of the first things you should check is the carburetor. Over time, the carburetor can become out of adjustment, which can cause all sorts of problems. Fortunately, it’s relatively easy to adjust a Poulan chainsaw carburetor, and only takes a few minutes to do.
First, make sure that the chainsaw is turned off and cooled down completely. Then remove the air filter cover and spark plug boot so you can access the carburetor. Locate the two screws on the side of the carburetor (one is labeled “L” for low speed, and one is labeled “H” for high speed).
Using a screwdriver, turn both screws clockwise until they’re snug against the stop inside the carburetor housing. Don’t overtighten them! Now start up the chainsaw and let it run for a minute or so.
If it seems to be running smoothly, you’re done! If not, you may need to readjust slightly. Hopefully this quick tip helps keep your Poulan chainsaw running like new!
