Your welcome. I rode new years eve here in nebraska and I think it was about 40 degrees. I ran 45 pilot and a 170 main. Probably would have been better with a 172. You have to remember that its going to take longer to warm up so it may seem a little sluggish until it gets up to operating temp. But it should be ok with that jetting.
