Okay, that's better. As I said, check for a good spark first.
The three things you need are air/fuel (you say the carb is not hot and there is fuel coming out), spark (there is good stuff on electronic ignitions in the tech section), and compression.
Since the motor is fresh, we will assume at this point that the rings and timing are okay. The part that worries me is the slowing down before dying. That's usually not a sign of an electrical issue, although it can happen. Did the engine get hot, did the oil pressure drop?
When you can check for spark, let us know.
