The last trimmer I had with John Deere gave me fits until an experienced mechanic informed me that the directions were faulty... that he'd argued the point with manafacturers... He got me on the right path. I've moved, haven't the mechanic around, and purchased a new trimmer. Started first time like a champ. Second week, no go. Not even a gasp. Checking the plug I find it completely dry, which is really puzzling. Instructions go; 1. prime 10 times slowly 2. put in choke position 1 3. pull cord five times. 4. put in choke position 2 5. pull cord until start. If no go, start at top again. Any help out there? Lesson finally learned - buy from dealer that supports products.
