Go read the info
Nothing trying to be rude or anything, but seriously, read the powerpoint persentation on "target EGT" on that link I sent, and also read the Deakins articles on "leaning". It will answer all your questions.... And Oh, BTW, you can run just about any engine LOP, injected's are easier, but Carbs (use carb heat to make it run LOP) work too. 4 or 6 cyl. And yes, an engine monitor helps a bunch!
this whole topic has one thing in common. Health of your engine. Read as less oil usage, less plug fouling, less wear and tear, more fuel effeciency, better power when you need it, and much better cooling.
I had a million and one questions as well, until I started researching this whole topic. I'm not trying to get into the LOP vs. ROP debate.... You asked about climb technique, and the powerpoint on "target EGT" is spot on to answer that topic. And the newer generation of engine management technique says, prop and throttle full forward and leave em until you are at altitude. Enroute climb is just setting the prop to climb pitch from then on.
Perhaps the one piece of info that I didn't mention. Of course, if you get to your altitude (with prop and throttle forward), and you still have more manifold pressure than you want to turn in cruise, of course, pull the MAP back as well. and set the cruise RPM.
One curve ball with "target EGT". You have to establish is at a "sea level" airport. So for example, the basic process is ... At a Sea level airport, take off with full rich mixture. At 600', look over and see what your peak EGT is. That's your "target EGT". Now "whenever" you climb, continue to lean to that number. No more, no less. Remember that number as you'll use if forever more. At each airport, regardless of airport elevation, set that number on climbout and continue to lean to it. At high altitude airports, during runup, lean as needed and on climbout, at 600', readjust to your Target EGT.
Hope this helps, it's new, its different, it's gonna get all kinds of "nay sayer" comments, but it has changed the way I fly.
Sorry for the LOP comment, didn't mean to confuse you. That's really a Cruise setting. One that I'm going to try one of these days.... BTW, the whole LOP topic, also has benefit on descent and ignore any comments about Shock cooling, unless you are running a turbo, you *can't* shock cool your engine!
