Sounds like either bad gas or fuel starvation. Fill the tank up with good gas and check to make sure your petcock is in the right position. Also, if the tank was removed for the service, the vent line may have been pinched.
You might also check to make certain that the plug wires are fully seated, but that's the last thing I can think of.
If any of this works, please let me know.
Oh, and thanks, soldier!!
