I'd look at the fuel pump. Vacuum leaks. Maybe a stuck needle valve. Are you priming the carb when it starts and then dies?

Yeah When I First Start It We Prime I'll Check The Fuel Pump In The Morning... The Needle Valve Never Thought If The But Even If The Carb Is Getting Fuel Could If Be The Pump Still I Can See Fuel In The Line...

If this just started out of the blue, I'd say look at the accelerator pump. But since it started after you cleaned everything, it's gotta be some crud was dislodged and is plugging something up. I'd start with the fuel filter, and see if it is newly plugged up. If not, I'd pull the carb apart again, and after cleaning all the passages with carb cleaner, make sure to blow them all out with compressed air to insure any blockages are cleared. Just make sure all the springs and check balls are out first so they don't go flying into neverland.

I've Checked The Accelerator Pump And It Seams To Be Working But I'll Check It Again I Put The Carb Filter Back On And Took Off The In-Line One It Was Dirty And Now Cleaned But It Wasn't Filtering Before It Was Loose And Bouncing Around Doing Nothing...

Welcome to the site first of all. did you adjust the carb at all. Maybe your giving too much fuel. Were your plugs bad before. I had the same problem with my truck. Carb had junk it in and caused the floats to stay too high. Fouled the plugs out. Clean your plugs really good and try to start again. If it does adjust the carb and clean the plugs good.
