Troubleshoot Carburetor

• 1). Turn your chain saw on and let it idle. If your saw stalls out on idle or if the chain rotates, your engine speed is set improperly.
  
  
• 2). If your chain rotates on idle, reduce the engine speed by turning the idle screw counter-clockwise.
  
  
• 3). Increase the engine speed if your saw stalls out by turning your idle screw clockwise.
  
  
• 4). Repeat the adjustments until your chain saw runs at a proper speed and cuts wood without stopping.
  
  
• 5). If the chain saw still doesn't start, bring it in to a Poulan repair shop.
