Every year I spent time taking the trimmer apart and cleaning the carburetor. It got to the point where it wasn't even working properly. If I knew it was that cheap to buy, I would have done it a long time ago. I redid everything, even the fuel lines. Fuel hoses were a pain to replace. I had to drill some holes to replace the hoses. Replaced everything in 1.5 hours, now it works like new. I have to play with the idle to make it slow enough so the trimmer doesn't spin. no wow what's up
