Craftsman String Trimmer starts then dies
I have a 2 year old Craftsman string trimmer (Model # 316.791810). After pulling it out of the garage for the winter it would not start so I rebuilt the carb and it worked great for about a month. Then it started to idle very hard and finally would shut off where I could not start it again. I finally got it to start and run anywhere from 2 seconds to 1 min. but it runs rough and will not keep going. I have replaced the spark plug, recleaned the carb, re-adjusted the carb needle, checked the fuel lines, adjusted the idle screw and the carb screws, cleaned the air filter, cleaned the muffler plate, and this thing still won't run! I don't understand, it was running great and just died! Please help...
