Hello guys, I have been having this problem with my DA 50 right after installing it into a new bird (it never did that before). I would set the low needle for the best transition and set the high to 2 full turns. She would fly nicely for 5 mins or so then when I try to transit from idle (in the air) it would want to die as if it was too lean but she would idle fine as soon as I pull back the stick to idle. it seems as it goes lean when it heats up in flight which does not make sense to me, I know as engines heat up they need less fuel or in other words they run richer but in my case it acts the opposite at the beginning of the flight it would burble and act rich, then a couple of minutes later she would run beautifully and soon after it would act as being too lean (would not transit) and this is when I land and check the engine temperature to find out that the engine is too hot. Is it only a matter of adding more fuel at idle or it's an air flow issue, and finally what the symptoms of an over heating engine, would it be wanting to die during transition?


oh I almost forget, my plane is extereme flight look alike Yak.


Thanks a lot
