Yep, cold weather is normally accompanied by low humidty. So there is not as much moisture in the air. Fatten her up!

Run richer and you can add aluminum foil around few fins to make sure it goes up in temp.

When running in cold weather i take an old sock and wrap the fins of the cooling head, use a hot plug, richen the motor.
