Master the Art of Adjusting Your Poulan Chainsaw Carburetor for Optimal Performance

Poulan chainsaws are known for their power and efficiency, but sometimes they may start to run poorly or stall while in use. One common cause of this problem is an improperly adjusted carburetor. Fortunately, adjusting a Poulan chainsaw carburetor is a simple process that can be done at home with the right tools and knowledge.

The carburetor plays a crucial role in regulating the fuel and air mixture in the engine, and if it’s not working properly, it can cause the chainsaw to run poorly or even fail to start. However, adjusting the carburetor on a Poulan chainsaw is a relatively simple process if done correctly.

It’s important to start by understanding how the carburetor works and the different parts involved in its operation. This will give you a better idea of what needs to be adjusted and how to do it properly.
When adjusting the carburetor, it’s important to make sure you’re working in a well-ventilated area and taking appropriate safety precautions to avoid injury. This includes wearing protective gear such as safety glasses and gloves, and making sure the chainsaw is turned off and the engine is cool before making any adjustments.

The three main adjustments to make on the carburetor are the idle speed, high-speed adjustment, and low-speed adjustment. These can be adjusted using a screwdriver (or sometimes a special splined tool is required), but it’s important to make small adjustments and test the chainsaw’s performance after each one to ensure you’re not causing any damage.

Poulan Chainsaw Carb Adjustment

Before adjusting the carburetor, it’s important to ensure that the air filter is clean and that the fuel filter is not clogged. A dirty air filter can cause the engine to run poorly, while a clogged fuel filter can restrict fuel flow and cause the engine to stall. Once these issues have been ruled out, it’s time to move on to the carburetor.

Simple Poulan Chainsaw Carburetor Adjustment

The first step in adjusting a Poulan chainsaw carburetor is to locate the adjustment screws. These screws are usually located on the side of the carburetor and are marked with letters that correspond to the different adjustments. The letters may vary depending on the model, but typically they will be L, H, and T. The L screw controls the low speed adjustment, the H screw controls the high speed adjustment, and the T screw controls the idle speed adjustment.

To begin the adjustment process, start the chainsaw and let it warm up for a few minutes. Then, turn off the chainsaw and locate the L screw. Using a small screwdriver, turn the L screw clockwise until it stops, then turn it counterclockwise 1.5 turns. This is the starting point for the low-speed adjustment.

Next, start the chainsaw again and let it run at idle. Turn the T screw clockwise until the chainsaw starts to stall, then turn it counterclockwise until it idles smoothly. The idle speed should be set so that the chain stops moving when the throttle trigger is released.


Once the idle speed is set, it’s time to adjust the high-speed setting. To do this, hold the chainsaw at full throttle and adjust the H screw until the engine sounds smooth and there is no smoke coming from the exhaust. If the chainsaw bogs down or stalls when cutting, the high-speed setting may need to be adjusted.

It’s important to note that adjusting the carburetor can be a delicate process, and it may take some trial and error to get it just right. If the chainsaw is still not running properly after adjusting the carburetor, it may be necessary to seek the assistance of a professional. Additionally, it’s important to use the correct type of fuel and oil mixture, as specified in the owner’s manual, to ensure optimal performance and longevity of the chainsaw.

It’s important to always refer to the owner’s manual for your specific Poulan chainsaw when adjusting its idle speed and maximum RPMs. Exceeding the maximum allowed speed can cause serious damage to your chainsaw and potentially lead to safety hazards. It’s also important to make sure that the chain stops moving when the engine is idling to avoid any accidents or injuries. If you’re unsure about how to properly adjust the idle speed or RPMs on your Poulan chainsaw, it’s best to consult a professional or contact Poulan’s customer support for assistance.

In conclusion, adjusting a Poulan chainsaw carburetor is a straightforward process that can be done by anyone with a little bit of knowledge and the right tools. By properly adjusting the carburetor, you can ensure that your chainsaw runs smoothly and efficiently, and is able to tackle even the toughest cutting jobs. Remember to take your time, be patient, and always follow the manufacturer’s instructions and safety guidelines when working on your chainsaw.


Finally, adjusting the fuel ratio can also help to improve the performance of your Poulan chainsaw. This involves adjusting the air/fuel mixture screw to achieve the right balance of fuel and air for optimal engine performance.
