Squirt a little fuel down the throat of the carb. If it then fires, you have a fuel delivery problem. Just because something is new does not mean it is good. This past summer, I purchased a Corvair in a non running condition. I went ahead and replaced all the ignition components before attempting the first start. I would start and run, but a soon as it got warm/hot, it would die and not restart until it cooled down. Replaced condensor and coil again and the problem went away.
