I have a Weedeater Featherlite that has provided great service for a few years. When I tried it after it had sat for about 6 weeks it would not start. I mixed a new fuel batch and tried without success. I changed the spark plug and cleaned out the air filter that appeared to be dripping fuel. Again no luck. Using the choke does not help either. The engine spins freely as I have always provided 40:1, but other than a few pops on the first pull I hear no ignition sound. It was sitting on its head, could this have caused the problem, or is it possibly the coil. I would appreciate your assistance...

Do you have compression? Do you have spark? And the filter being full of fuel is an issue in its own. Could be the needle valve is stuck open in the carb. I suggest a thorough cleaning of the carb if you have compression and spark.
