Edit: Just went up for a flight (cross country quick mission), that worked great, thanks! The other hurricane is a bit easier to keep the RPM at a nice level and the engine shakes a lot less (only on start up now, rather than in flight).
With this hurricane, mixture is full back = rich? When would I use it pushed forwards, other than a little bit at takeoff- at high altitudes where air is thinner so less fuel is needed?

Yes you move the Prop lever to control the prop rpm but at low boost it will fall away anyway.
Leave Mixture on Rich (lever back). It could be leaned (lever forward) for economic cruising wih restrictions on boost/rpm but lets face it, you're not going to be doing that unless you enter into a 2.5 hour patrol scenario
By the way if you fly the Spitfire as modelled at the moment the lever is the wrong way round - forward is rich. Should be fixed sometime.
You can play with the mixture, leaning it gradually until the yellow exhaust flame just turns blue but then you are on the edge for those particular circumstances (boost etc) so I don't bother. We're never up long enough to run out of fuel and we can keep the engines reasonably cool by boost and rpm. Focus more on basic tactics like being above the bandit rather than below him and get out before you lose the advantage - ahem.... do as I say not as I do!
I'm only trying to give an operating guide, I'm not trying to give you the perfect setup for various conditions. You could research those in the Pilots Notes and see if the modelling is perfect or not but frankly those are test scenarios. Some guys worry about things like "the flight model delivers 8mph below the XXXXX test data". Well, all a/c were different anyway with no guarantee of returning that test performance and its unlikley you'll be in a perfect "test" situation when you spot that bandit. And as a newbie to the Squadron do you think they'll give you the factory fresh aeroplane? No, the boss gets that one, yours is the one with the near-expired engine
