To each his own I guess.

I have gotten used to glancing at the EGT on my takeoff rolls just to
make sure things are feeding fuel and air, and also running right. I
look for something about 50 to 100 deg F on the rich side of peak.
EGT also tells me if I have loaded up the things with carb ice while
waiting for takeoff. It is the only cross-check that I have to figure
out if the air/fuel metering system is behaving right, and that the
engine is properly extracting energy from the combustion process.

Personally I feel that any new engine installation (such as in a
homebuilt) should have at least a temporary EGT until the
idiosyncracies (sp?) of the air intake system are proven out. I've
seen/heard of several aircraft that have been excessively lean
(especially in the winter) or rich to the point of stumbling when carb
heat is added. The technique of getting a badly iced engine back
requires aggressive leaning, but I don't see that taught anywhere.

How do you lean a constant speed prop aircraft without EGT? I agree
that leaning a fixed pitch prop on the run without an EGT is not good
practice unless you know the engine.

Maybe I am more into this because I am using autofuel.
