We have a problem because the Hurricane (and Spitfire) mixture outputs are reversed to what they should be.
Engine Start:
Set mixture to RICH in cockpit.
Be aware that currently the mixture selection is reversed in the cockpit, RICH = WEAK and vice versa. On the DH prop Hurricane move the mixture lever all the way forward until it is fixed when it will be all the way back. On the Rotol Hurricane, closing the Throttle also closes the Mixture to RICH, which is what it should do on both Hurris. But remember RICH is in fact LEAN atm so with the Rotol move the throttle forward to just clear the START label then move the mixture up to just behind it, thats as RICH as you'll get without over-opening the throttle for startup. When running, handle the Rotol Hurri throttle opening carefully, moving the mixture lever forward behind the advancing throttle as much as engine running will allow. This should all go away once the problem has been fixed. See

Temps for takeoff:
Oil temp: min 15'C
Coolant temp: min 60'C (according to Pilots notes)
Open Radiator until you are in a position to manage the engine temp with it (70C - 90C, max 105C)
Takeoff prop is usually 3000 rpm, max boost. Climbout around 2600 with boost reduced around 4lbs. Combat in the region of 2600-2800. Cruise anywhere from 2000-2400, typically boost 0. These are from memory of the pilots notes but they should help.
