idle circuit shuts off in the morning

[64 200 ranchero]

ive been having a hard time starting my car in the morning, it will start no prob, but after it runs for a few min it shuts off unless i pump the gas pedal to keep it running. once it warms up it is ok, any other time of day my car will drive fine, is my carb getting too cold, it has been low 40's at 5 am

Do you still have a choke on the center carb?
