Our weedwacker hasn't been working for a while now. The carb, filters, and fuel lines are all clear. For some reason it is not working at all. The spark plug is working, producing a spark. Tried seeing if it was flooded and that wasn't the solution either. Any ideas?

Hi,
Try replacing the inlet screen in the carb. Another very rare occurrence is the shearing of the flywheel key; it is cast into the flyheel and requies the replacement of the flywheel(it will still have fire under this circumstance.)
Peace,
