Here it only gets down into the low 30s so no big deal, thing is it can happen over night, like A couple of weeks ago. It was 83 and I was flying, the next day it was 36 and our engines are tuned for over 100, the next morning it was in the mid 60s?? This time of year it is A small problem to get the engines in correct tune so you don't have to dink with the needel valves. Everyones engines are hard to start the first time in the morning now. I learned last year, all my glow engines need to have the high end turned out four clicks, no big thing, I just run them fat until the weather warms up again next spring. For early morning my friend from NY had me start putting in A few drops of lighter fluid into the carbs and they fire right up. Most of my engines I can't get to the carb to do this so I just keep A good charge on my starter battery and roll them over until they start.
