Just from my little experience, but if it is tough to start cold, as the temp drops. I usually bump up the pilot. It is also a good idea to bump up the main if getting run hard & going from 80 degree weather to 40 degree. Actually there is a rule of thumb for every 10 degrees, but some carbs compensate better. Then go back down when the outside temp warms up. I am sure kicking it over real slow twice would help that situation out in more ways than one.
