Historically, I mean for the last 25 years, when it gets good and warm, like after 20-30 minutes of cutting, it tries to die, you can feather the throttle for another 10-15 minutes but then when it dies it's done until it's cold.
It was getting worse this fall, less than 5 minutes before it would die, so I took it into our licensed repair shop and now it'll idle but chokes with even 1/4 throttle. It'll be going back into the shop tomorrow.
But this has been an issue since year one. My Dad took it to two different shops when they couldn't fix it he gave it to me. I've taken it to three places and I've never gotten a full day of use from it.
My Husqvarna runs all day, day after day. My buddies Stihl runs great. But my Stihl is a POS.
