To adjust the carburetor on a Poulan Pro chainsaw, first ensure that the chain is not engaged. Next, remove the air filter cover and carefully pull out the filter element. Then locate the adjustment screws on top of the carburetor- these are usually labeled as H (high speed) and L (low speed).
Using a flat head screwdriver, turn each screw clockwise to increase engine speed or counterclockwise to decrease it until you reach your desired setting. Finally, reassemble all components and test your settings by starting up your chainsaw and running it for a few minutes at idle before attempting any further operation.
- Step 1: Make sure the chainsaw is turned off and unplugged before attempting to adjust the carburetor
- Step 2: Locate the two adjustment screws on the side of the carburetor, labeled “L” for low speed and “H” for high speed
- These are usually marked with an “L” or “H” near them
- Step 3: Turn both screws clockwise a quarter turn at a time until they stop, then back them out one-and-a-half turns each
- This will set them to their factory default settings which should provide optimal performance
- Step 4: Start your chainsaw engine and run it at full throttle for several seconds in order to warm up its internal components
- Then let it idle on its own without touching any controls or buttons while you make adjustments to the carburetor settings
- Step 5: Turn only one screw (either L or H) at a time in small increments, about 1/4 turn per adjustment, until you reach desired results from your engine’s performance (for example if you want more power then increase both L & H)
- Repeat this process until you’ve achieved satisfactory results from your Chainsaw’s performance as well as improved fuel efficiency and emissions output levels

How Do You Adjust the Carburetor on a Poulan Chainsaw?
Adjusting the carburetor on a Poulan chainsaw is a relatively simple process that can be accomplished with just a few tools. Before adjusting, make sure the saw is cold and off. Start by loosening the two screws located near the engine – these are known as jamb nuts.
Next, loosen and remove the air filter cover which will allow access to the main jet screw. This screw should be adjusted in small increments until you hear an increase in idle speed from your saw; this indicates that it’s set correctly for optimal performance. Once done, replace both jamb nuts and air filter cover before turning on your chainsaw to test its new settings.
Make sure all connections are tight so no fuel or exhaust leaks occur during operation! Finally, if necessary readjust either of these screws again until you get the desired performance from your Poulan chainsaw; then you’re all set for some safe cutting!
Why Does My Poulan Chainsaw Die When I Give It Gas?
If you’re having trouble with your Poulan chainsaw dying when you give it gas, there are a few potential causes that could be the culprit. The most likely cause is an air leak in the fuel line or carburetor, which allows too much air to mix with the fuel and causes your engine to sputter out.
Another potential issue could be a faulty spark plug or ignition coil, which can prevent the spark from igniting the fuel mixture inside the cylinder.
Lastly, if your chain saw has been sitting for some time without use, it’s possible that debris has built up in its lines and filters; this can block proper airflow through the system and impede performance. To diagnose these issues properly, it’s best to take your chainsaw to a professional repairman who can check for any of these problems and help get you back up and running quickly!
What are the L And H Screws on a Chainsaw?

The L and H screws on a chainsaw are two of the most important components when it comes to ensuring your saw runs optimally. The “L” screw is the low-speed adjustment screw that controls how fast or slow the chain moves around the bar, while the “H” screw (also known as high-speed) is responsible for controlling how much fuel is fed into the combustion chamber.
Adjusting these screws correctly will help ensure your saw has enough power and won’t overheat or bog down due to too much fuel being consumed.
It’s important to remember that both screws need to be adjusted in tandem – if one is set too high, then it can cause problems with either stalling or excessive vibration from an unbalanced engine.
Additionally, you should take care not to overtighten either of these screws as this could result in damage to their threads and potentially lead to further issues with performance down the line.
How Do You Adjust the Carburetor on a Poulan Pro 42Cc?

Adjusting the carburetor on a Poulan Pro 42cc is an important step in keeping your chainsaw running at peak performance. This process requires some basic tools and knowledge of how to use them safely. Begin by disconnecting the spark plug wire from the spark plug, then remove any debris that may be blocking the air filter or fuel lines.
Next, locate and loosen the screws that secure the carburetor body to its mounting plate so you can access it for adjustment. You’ll need a screwdriver to adjust both idle mixture screws located on either side of the main jet assembly; turn each clockwise until they are snug against their seats before turning each counterclockwise one full turn as a starting point for adjustments.
Afterward, start up your saw and let it run while adjusting so you can assess its performance; if necessary make further adjustments while monitoring engine performance until it runs smoothly with no stalling or hesitation under load.
When finished, ensure all screws are tightened securely before replacing your air filter and reconnecting your spark plug wire back onto its terminal – congratulations! You have successfully adjusted your Poulan Pro 42cc Carburetor!
