I had similar trouble when my lawn mower wouldn’t start after winter storage. The dealer didn’t respond for days, so I checked https://husqvarna.pissedconsumer.com/customer-service.html for direct support options. A regional technician returned my call within a day, explained what to check for stale fuel, and even mailed replacement parts under warranty. It was good old-fashioned service that reminded me some brands still care about proper maintenance advice.
