Step-by-Step Guide to Setting the Carburetor on Poulan Chainsaw

Adjusting the carburetor on your Poulan chainsaw is a straightforward process that can optimize its performance. Follow these steps carefully:

  • Locate the Adjustment Screws:

  • On your chainsaw, you’ll find two adjustment screws: one for the low-speed adjustment and another for the high-speed adjustment.
  • The low-speed screw is usually marked with an “L,” while the high-speed screw is marked with an “H.”
  • Preliminary Settings:

  • Before starting the adjustment process, turn both screws clockwise until they gently stop. This is your starting point for adjustments.
  • Starting the Engine:

  • Start your chainsaw and let it warm up for a few minutes. This ensures that the engine is at operating temperature for accurate adjustments.
  • Adjusting the Low-Speed Screw:

  • Use a suitable tool to turn the low-speed screw to achieve an optimal idle speed. Turn it clockwise to increase the idle speed and counterclockwise to decrease it.
  • Adjusting the High-Speed Screw:

  • Next, adjust the high-speed screw for the optimal top-end performance of your chainsaw. Turning this screw clockwise will lean the mixture, while turning it counterclockwise will enrich it.
  • Fine-Tuning and Testing:

  • After adjusting both screws, fine-tune them to achieve smooth operation and maximum power.
  • Test your chainsaw under different load conditions to ensure it runs smoothly and efficiently.
  • Always wear protective gloves and follow safety guidelines when working on your chainsaw’s carburetor. This ensures a safe and successful adjustment process.
