Craftsman Weed Eater

I have a Craftsman weed eater that stopped running after I switched it to True Fuel (40:1), it ran once with the new fuel, and hasn't since. Things I have done since, 1) Changed to regular (40:1) fuel, 2) Cleaned Carburetor 3) Changed primer bulb 4) Changed fuel intake line (not filter yet), 5) Changed recirculating fuel line 6) Replaced carburetor, so lets stop there, fired right up, ran for a moment, kept dying within minutes, on choke or off, continued that sequence for a while, then wouldn't fire period. 7) Changed spark-plug, and will not fire anymore.

I am looking for any other thoughts on what I can do. I appreciate any help. Any questions let me know.

Here is the unit from Repair Clinic
