Try choking it, manually. Take the air filter/foamy deal off (plastic cover included) and stick your thumb/hand over the opening of the carb and give the starter cord a pull or two. If it start to fire up, kind of take your finger/hand off the carb a little bit so the engine can get more air. You might have to do this a few times and modulate your finger/hand over the carb to keep it running.
For whatever reason little two strokes do weird sh*t like that every now and again...weed eaters, chain saws, you name it...
