I'm a long-time flight simmer, but I'm finding I need a tutorial not knowing what is modeled and what isn't.  For example, on the abbreviated checklist (before starting engines), you're to check the stall warning.  I searched for a lengthy time and couldn't figure that out, so it's not modeled I guess?  There's also a series of fuel pump checks to go through, but the engines start fine without ever touching the fuel pumps.  I admit I know little about this type of aircraft, but a written tutorial by Carenado would help getting familiar with this bird.  

Look here, it helps:

 

 

You should have your engines RPM set both to MIN/LOW and your throttles set at GI. All Fuel Pumps ON (1 & 2). STALL warning sign seems not to be functional.
