BF-109 Prop Pitch Lever

[VF-51_hawg]

I have been flying IL2 for years and years and finally took the plunge into CoD. Its pretty cool so far I was having a blast getting used to the 109. I was wondering if there were any good references out there on how the prop pitch lever works. Or if someone has created a flight manual for this bird. The documentation that came with the game is pretty sparse.
I noticed the prop pitch lever seems to have 3 fixed positions and unless its in the upper most position when I start the engine I wont get any power regardless of where you place the lever after the engine is running.

Any help would be greatly appreciated.
