  • Clogged air filter
  • Dirty spark arrestor
  • Carburetor issues
  • Misaligned high-speed screws

Inadequate Husqvarna Chainsaw Fuel Ratio

Dirty Husqvarna Chainsaw Spark Arrestor

Dirt is impossible to avoid. It can get to everything, including a spark arrestor and a spark plug, even with the smallest opening.

  • Clogged carburetor
  • Imbalanced fuel mixture
  • Overheating/excessive smoke release
