Why does my Husqvarna ST 424 Snow Blower have decreased power?
- D
  dawnmaloneSep 14, 2025
  Decreased power in your Husqvarna Snow Blower can stem from a few sources. Check that the spark plug cable is securely connected. If you're throwing too much snow, try decreasing the speed and width of the swath. Ensure the fuel tank cap isn't covered in ice or snow. A dirty or clogged muffler can also cause power loss, so clean or replace it. Ensure proper cable length and clear any blockages from the muffler or air intake of the carburetor, making sure the engine is cool first. For fuel injector issues, contact an authorized service center.
