I live in Canada and I don't use a choke, I've pulled mine off of my last two carbs. I don't drive my car from mid November to the end of February but all I do is pump it a few times with the electric pump going and then nurse it until it's warm. I think it's a good anti-theft device because the average thief will be in too much of a hurry and stall the car 5 times giving you more chances to hear the car start and load up the .357
