My Husqvarna weedeater was always a bit crappy. Then it went from bad to worse and I took it into the Husqvarna people for them to sort it. It was in and out of the shop about 3 or 4 times then they offered a big discount on another brand. I asked for one of their tuning screwdrivers and then found the shop's tuning was WAY out. Sure it doesn't idle but it's got way more revs, doesn't bog and die (just like your one is doing), and a LOT more power
