Just gonna copy and paste my post from the ATAG forum here for those who may find it interesting.

OK, Testing done, my findings are:

DH Hurricane.....mixture is back to front, full rich is all the way forward, lean is all the way back....might be why the DH is a pain to start, get lever all the way forward when u push throttle forward.
Hurricane Rotol...modelled correctly
Hurricane 100oct...modelled correctly

Spitfire MkI....back to front...as per DH Hurricane
Spitfire MkIa...modelled correctly
Spitfire MkIIa...modelled correctly
Spitfire MIa_100oct...modelled correctly

Blenhiem MkIV...couldn't see any change. It flew just fine with the mixture where it should be, all the way back. In-game the mixture throttles are all the way forward at spawn.

Made a semi-dark early morning map and these findings are based on yellow and blue flames from the exhaust. If these are modelled incorrectly then all bets are off.
Not sure if it's absolutely needed but I found running the mixture throttle all the way up and down seemed to have a settling in effect after u takeoff (take that for what it worth, maybe nothing).
Now if this is all correct then it should help us with correct engine management and fewer burnt engines. There are other factors of course like rate of climb (keep at 180mph or above), radiator settings
(I aim for between 35 to 50% depending on what I'm doing aiming to keep engine temp under 110* water temp), prop pitch (the higher u go the coarser u will need to run it...been using 2400 when up at 16 to 19000ft) and throttle adjustment...u don't necessarily need hammer down all the time, proper engine management will require adjusting throttle to where it's needed.
Joining the Allied side means u are gonna need to learn how to fly. If u don't want to learn how to fly then get in a 109 E4 and just enjoy urself
