Cold weather makes engine run lean. What about the idle and mid range circuts. Can you give it a little more accelerator pump. Usally that helps with stumble. Also is the throttle linkage opening the before the acc. Pump is moving. This could casue the type of problems you talking about.

Do you have vacum and mech advance hooked up? Done any tuning with them.
