Turning the main jet out 1/2 turn in the winter more than it was in the summer is always a good idea. Cold, dense air needs a richer mixture. But, any more than 2 1/2 turns out usually means a problem in the carb.
Do one thing at a time; for now, concentrate on spark. If it won't jump 1/4" in open air, you have a problem.
