In the colder weather, you will have to run a richer setting than in the warm weather. I know the Traxxas book says to run no hotter than 270*, but mine ran the best at 280-290. I'm not suggesting that you run yours that hot. I was not running Traxxas fuel, which will help it run a little cooler. The biggest thing, watch the smoke. If you are running that hot, you should richen up a little, but watch (and listen to) the way it runs. Does it sound like it is "choking"? If so, you may be too rich. does it sound like it is trying to cut off? If so, you may be too lean. If it is running smooth, and there is a lot of smoke, you should be about right. Sometimes, if it is running GREAT, but hot, the High speed may be fine, but your low speed is too lean. Let it idle for about 15-20 seconds, then grab the throttle. Does it sputter, and spit, then take off? you are too rich on the low speed. If it won't idle for 15 seconds, and the RPM's shoot up before it dies, you are too lean. Hope this helps.

Anybody feel free to correct me if I'm wrong.
