It may sound counter intuitive, but I would check the entire ignition system, spark plug wires and check to see if there is oil in the spark plug galleys due to a faulty seal fouling the plugs.
I know it may seem like a fuel problem pertaining to the discrepancy of hot and cold temperatures, but it could also be a coincidence. If the car has been sitting for a while, and the plugs have gotten fouled for some reason, this engine behaves in the manner you explained, especially if you still have the original factory distributor wires installed. This engine from my experience is extremely sensitve to ingnition stuff much more so than gas stuff.
