Craftsman Trimmer starts then dies
I have a 2 year old craftsman string trimmer (model number 316.791810) that starts up for about 2 seconds to 1 minute and then dies. It didn't work when I pulled it out of the garage this spring so I rebuilt the carb and it worked fine for about a month until it started to idle really hard and became harder and harder to start until finally it wouldn't start at all. When it does start up for a second or two it runs extremely rough. I have cleaned the carb again, re-adjusted the carb pin, replaced the spark plug, put in fresh fuel, checked the fuel lines, adjusted the idle screw, adjusted the carb mix screws, cleaned the air filter and muffler filter, and even cleaned the fuel cap vent. I have no clue what's going on, I think that it may be getting too much or too little fuel. Please help!!!
