It sounds like it can be attributed to a lack of fuel pressure. Has the fuel filter been replaced in the past? When it is cold it requires more enrichment, like the choke on, and if you have low volume/pressure you may notice it when cold. I would lean towards fuel pressure, another thing to check is for a leaking fuel pressure regulator, where raw fuel is leaking past the diaphragm into the vacuum line and induction system. These are usually not cold weather related, but it is another possibility.
