Hard starting when cold

Talk about luck i was just about to post about something similar. I got a 63 with a carter single barrell.I pump the gas once its fires in about one revolution runs for less than two seconds and dies pump the gas one more time fires in a half of a revolution right into fast idle and im on my way. The only exception to mine is it does it no matter if is 20 degrees or 80 degrees outside.My wife thinks its funny but i tell her it fires second time everytime.
