If you are actually in Vista, that does not even fit the definition of "cold."
What are we working on, /6? 318 2bbl? Six two barrels on a Man-a-fre?
What do you do to start it? Pump the gas pedal a couple times? Floor it once to set the choke?
Have you checked the accelerator pump to see if it's giving a shot of fuel?
I agree, probably a choke problem, maybe whoever put it together got the linkage all bound up and it's not closing?
