You mentioned changing the battery but another cause might be battery -- Lower temperature and the resulting reduced efficiency would bring any problems out. A lower CCA capacity compared to stock, a marginal cell or too small a cable could reduce the output voltage under starter load. Anything less than about 4.5 - 5v at coil when cranking and the spark will be minimal -- perhaps to the point of not being able to jump the gap since plug efficiency is also reduced to some degree when cold.

I remember Dad used a dipstick oil heater during winter and also kept the charger at the ready but never had any significant starting issues.
