Why my Husqvarna 525HE4 engine does not start?
- J
  Joanne JenkinsAug 16, 2025
  If your Husqvarna Trimmer engine won't start, several factors could be at play. It could be due to the starter pawls not moving freely, which requires adjusting or replacement. The fuel type might be incorrect, necessitating a drain and replacement with the correct fuel. A dirty or wet spark plug can also prevent starting, so ensure it's dry and clean. Other potential issues include an incorrect electrode gap, which requires cleaning and adjustment, or a loose spark plug, which simply needs tightening. Also, you can clean around the starter pawls and speak to an approved servicing dealer.
