Classic/Antique Car Repair: no start after carb change, 67 camaro, fuel line

Question
I just put a new carb on my 67 camaro and once I finished she started right up and was running at 1500 rpm.  I let it run for a while then turned it off to make sure I had no leaks or anything, when I tried to restart the car it just turns over and never really tries to run.  What can this be caused from and how do I fix it?

FRANK:
Is the ful pump working, check the fuel p.s.i. if you have a gauge. and check the fuel filter. if dirty replace it. it could be that something was sucked up into the carb or fuel line. or the excyl. pump is bad. can you take it back to where you got it from ???>..>
