TB90BC Bushcutter-Help

[Boyde]

I give up, I need help. I have been working on my Troy-built TB90BC Bushcutter. It is old, but still use to work. It will run on choke. Idles great and runs great for about 30 seconds, then just dies. I have cleaned the Zama C1Q-P18A carburator in my ultra sonic cleaner over night. (Before this it would not start). New sparkplug, new diaphragm, new gasket, try with gas cap off. It will run on choke forever. It reves up real clean, idles at a good rpm. Then just dies. I am going to try to attach a video and two still pics.
Please help.vedio of TB90BC

Have you checked the fuel pickup and fuel lines? It sure seems like it's not getting enough fuel.
