I bought this trimmer from Walmart. The only brands they had available were Poulan, Weed Eater, or Black & Decker. I saw on Amazon that there are many trimmers by the brand Weed Eater being sold refurbished, so I decided to avoid that brand. I took it out of its box, read the manual and turned it on. It started very easily, but it wouldn't Idle (the router kept spinning at high speed). I fiddled with the screw that adjusts the carburator with out success, then I concluded that it's probably a compression problem. The starting cord hangs by about an inch, there's no tension!This is extremely frustating and customer service is not making it any easier. After some online searches, I discovered that the Poulan and Weed Eater brands are owned by the same company. I would advice everyone to instead buy a Hitachi or Black & Decker.
