Adjust a Poulan Pro chainsaw carburetor by locating the L, H, and idle screws, setting them to factory specs, then fine-tuning for optimal performance.
Understanding how to properly adjust the carburetor on your Poulan Pro Chainsaw is essential for ensuring your equipment is running optimally. This guide will provide you with a step-by-step approach.
Adjusting the carburetor of your Poulan Pro Chainsaw can seem daunting, but with the right instructions and tools, it’s a task you can complete confidently. A well-tuned carburetor ensures your chainsaw is efficient, reliable, and ready to tackle any job. Let’s dive into the process.
Safety First
- Ensure the chainsaw is turned off and has cooled down.
- Remove the spark plug cap to prevent accidental starts.
- Wear protective gloves to safeguard your hands.
Tools You’ll Need
The following tools are necessary to adjust your carburetor:
- Screwdriver set
- Tachometer (optional, but recommended for precise adjustments)
- Cleaning materials (cloth, carburetor cleaner)
Understanding the Carburetor
The carburetor on your Poulan Pro Chainsaw has three types of screws for adjustment:
| Screw | Purpose |
|---|---|
| L (Low speed) | Controls the amount of fuel at low speeds |
| H (High speed) | Controls the amount of fuel at high speeds |
| T (Idle speed) | Adjusts the idle speed |
Step-by-Step Carburetor Adjustment
- Locate the Carburetor Adjustment Screws: These are usually on the side of the chainsaw’s engine. Refer to your model’s manual for the exact location.
- Clean the Surrounding Area: Use a cloth and carb cleaner to remove any debris around the carburetor and adjustment screws.
- Adjust the Low Speed Screw (L): Start the chainsaw and turn the L screw clockwise until the engine runs smoothly. If it’s idling rough, turn counter-clockwise until you reach a smooth idle.
- Set the High Speed Screw (H): With the chainsaw running at full throttle, adjust the H screw. Turn it clockwise to lean the fuel mixture and counter-clockwise to enrich it. Aim for the highest possible RPM where the engine runs smooth without sputtering.
- Find the Ideal Idle Speed (T): With the chainsaw running, turn the T screw clockwise until the chain starts to move, then turn it counter-clockwise until the chain stops. This is your ideal idle position.
- Recheck and Fine-Tune: After initial adjustments, go back to the L screw and fine-tune for the smoothest running engine, then recheck the H and T screws as well.
- Verify with a Tachometer: If you have a tachometer, verify that the RPM readings are within the specifications laid out in your chainsaw’s manual for both low and high speed settings.
