Cannot get catby heat to work????
 

(In CEM mode) I have assigned 2 throttle (CH Pro Throttle) buttons for Carby Heat On and Carby Heat Off but they have no effect. When flying in cloud the carby just keeps icing up no matter how many time I pump or hold down the assigned button nor do I get a blue message saying carby heat on.
I have tried several keyboard functios but keep getting the "can't use this" beep.
Will someone who has found any working inputs for carby heat please tell me what they are using?

I got confused, removed my post.

Got the answer from the SimHQ forum, the GS20 and Blenheim are the only a/c to have carby heat modeled.

Another (to be added later??) omission for a flight sim with CEM.

I just had a quick glance through the reproduction Spitfire pilots notes that came with the Collectors edition and couldn't find any mention of a carby heat in the control description section, the labeled cockpit layout or the operating procedures section at the end of the booklet.

Did the Spitfire have a carby heat at this stage?

Cheers!

Spits, Hurricanes (i.e. Merlins) have no need for Carby heat due to engine design. The Sim modelled correctly in this regard.
