Terrence,
LOP starts when the mixture is LOP of course!
Sorry, for the smart ass response. There are a number of
good article on engine management and LOP operation written by John Deakin on “Pelican’s
Perch” on avweb.
There is also an excellent course on engine management given by
the GAMI folks called “Advanced Pilot Seminars” - http://www.advancedpilot.com/ I
took it and learned a lot.
The short answer to your question is that you want to be
approximately 50 deg LOP in most situations and it is best if all your
cylinders are LOP to the same degree.

Jeff,
May I ask for a little more detail on when the LOP
condition starts? Do all EGTs have to be LOPP, or is it when just the
leanest one goes? And, how lean constitutes enough to be considered LOP?
