So how do you adjust the carb for weather changes? I THOUGHT it was you needed richer as it got colder out. As the weather gets colder, it contains more oxygen. Therfor you need more fuel to compliment the larger amounts of oxygen. So I went from a 73/42 rod in my carb to a 70/42. It started blowing white smoke, too rich! Went back to the 73/42 and all was good. Did I go the wrong way?

Second, I finally found a edelbrock TV bracket. The only adjustable part on it is where the cable housing clicks into the bracket. At this point the bracket can be slid fowards and backwards. A generic bracket from checker can do this! Is that all that is supposed to adjust?
