Hi guys!

FSX is really starting do annoy me here. I've been trying to fly the JustFlight Dc-6B from NY to Chicago today, and after my extensive modification it handles fine. One problem though, I can't reach cruising altitude. Around FL110  all engines suddenly returned to idle, even with the throttles fully forward. Carburetor heat solved it, but is this supposed to occur at climb power? I don't think so. Then, at FL160, I lost power again, at climb power and with carburetor heat on. I had to glide all the way down to 9500 or so before power came back. This is annoying. Is there any way to disable the effect on a particular aircraft? The Dc-6B is the only piston engine plane except the B377 I fly this high, so I don't know if it will occur on any other planes. Help please!

Could it possibly having anything to do with leaning the engines, instead of carb ice. FSX starts to show the effects of not leaning the engines about 6000'. There would also be effects of super chargers, or turbo chargers, which I assume the plane must be equipped with. I don't have this model, but most of my piston plane flying is in these higher altitudes.

It has automixture enabled in the aircraft.cfg file to simulate the Auto Rich system the real aircraft has. I had the same problems when flying the aircraft unmodified too. I can reach FL250 as long as there are no icing in the area.
