This guide will walk you through the steps, making the process simple and clear. You’ll learn how to adjust the idle speed, low-speed, and high-speed settings. Let’s get your chainsaw running at its best!
Tools And Equipment
Gather all needed tools. A flathead screwdriver and a tachometer are essential. A clean cloth helps to wipe dirt. You also need a small brush. These tools ensure precise adjustments.
Wear proper safety gear. Gloves protect your hands from cuts. Safety glasses shield your eyes from debris. Ear protection guards against loud noise. A dust mask keeps you from inhaling particles. Safety gear keeps you safe.
Preparation
First, make sure the chainsaw is turned off and cool. Check the chainsaw for any damage or wear. Look at the chain, bar, and spark plug. Clean the chainsaw to remove any dirt or debris. This helps in getting a clear view of all parts.
Find the carburetor near the engine. It is usually covered by a metal or plastic cover. Remove the cover carefully. You will see the carburetor attached to the engine with screws. Note its position for easy reassembly.
Understanding Carburetor Screws
The high-speed screw controls the fuel at high speeds. Turn it clockwise to lean the mixture. This means less fuel. Turn it counterclockwise to rich the mixture. This means more fuel. Adjust until the engine runs smooth at full speed.
The low-speed screw controls the fuel at low speeds. Turn it clockwise to lean the mixture. This makes the engine run faster. Turn it counterclockwise to rich the mixture. This slows the engine. Adjust until the engine idles smoothly.
The idle screw adjusts the engine speed when idling. Turn it clockwise to increase the idle speed. This keeps the engine running. Turn it counterclockwise to decrease the idle speed. Adjust until the chain does not move while idling.

Initial Settings
Adjusting the carburetor on a Poulan chainsaw is key for optimal performance. Start by locating the adjustment screws. Fine-tune the settings to ensure the engine runs smoothly.
Factory Settings
The Poulan chainsaw comes with standard carburetor settings. These settings are preset at the factory. They are usually good for starting the chainsaw. The factory settings ensure the saw runs smoothly. It controls the fuel and air mix.
Adjusting To Baseline
First, locate the carburetor screws. There are usually three screws: L, H, and T. The L screw controls low speed. The H screw controls high speed. The T screw adjusts the idle speed.
Turn the L screw counterclockwise until it stops. Then, turn it back one and a half turns. Do the same for the H screw. For the T screw, turn it clockwise. Adjust until the chain stops moving.
These steps set the carburetor to a baseline. It helps in fine-tuning the chainsaw later. Always check the manual for exact instructions.
Fine-tuning The Carburetor
Start the chainsaw engine and let it run. Locate the idle speed screw. Use a screwdriver to turn it slowly. Turn clockwise to increase idle speed. Turn counterclockwise to decrease it. The engine should run smoothly without the chain moving.
Find the high-speed screw on the carburetor. Turn the screw clockwise until it stops. Then, turn it back counterclockwise one full turn. Start the engine and pull the throttle. Listen to the engine sound. Adjust until the engine runs smoothly at high speed.
The low-speed screw controls the mix at low speeds. Turn it clockwise to lean the mixture. Turn counterclockwise to enrich it. Adjust until the engine idles smoothly without stalling. The chainsaw should respond well when you press the throttle.

Testing The Chainsaw
Adjusting the carburetor on a Poulan chainsaw ensures it runs smoothly. Turn the idle and high-speed screws carefully. Test the chainsaw to check the adjustments.
Running At Idle
Start the chainsaw and let it run at idle. Listen for any unusual sounds. The engine should run smoothly. If it stalls or runs unevenly, adjustments are needed. Turn the idle screw slowly. Small turns make big changes. Find the point where it runs best.
Testing At Full Throttle
Squeeze the throttle fully. The chainsaw should speed up quickly. There should be no hesitation. If it bogs down, the mixture may be too rich. Adjust the high-speed screw. Turn it in small increments. Check performance after each adjustment.
Observing Performance
Watch how the chainsaw cuts wood. It should cut smoothly and quickly. If it struggles, the carburetor settings may be off. Check the saw’s response at different speeds. Make sure it runs well at all times. Proper tuning gives the best performance.
Maintenance Tips
Clean the air filter regularly. This helps the chainsaw run smoothly. Remove dirt and debris from the carburetor. Use a brush or compressed air. Keep the spark plug clean. Replace if needed. Inspect the fuel filter. Change it if dirty.
Adjust the idle speed. This ensures the chainsaw runs well. Check the H and L screws. These control fuel and air mix. Turn them gently. Fine-tune the throttle. This helps with power. Follow the manual for specific settings.
Seek help if the chainsaw won’t start. Or if it runs rough. Strange noises are also a sign. Professionals can fix it safely. Do not attempt if unsure. Safety first.
