Hello all,

I have a Brison 2.4, running on 40:1 Red-Line Synthetic racing oil, 20X8 Xoar prop. Until yesterday it was bullet prove.... Yesterday for the first time (5 gallons of fuel) I had 5 dead sticks in a row. It seems that while on the ground it runs great, but in the air it will die if you try to idle it, especially coming out of a dive, when you add throttle, it will die. I tried changing the fuel mixture and made no difference... The only factor that has changed since I flue it last was the ambient temperature - it was about 20 degrees cooler yesterday. Any one has any ideas what might be going on with it, or similar experiences?
