Thanks for the pointers. The articles are indeed quite good, but there
is something I do not understand. It seems the whole theory on LOP
operation is conditioned on having GAMI injectors, because the article
implies that you can not do LOP operations on "normal" engines because
of uneven fuel distribution causes roughness due to different cylinders
outputing different powers when you start leaning past peak. Am I
missing something here?

Not a lot. The article is not restricted to planes with GAMIjectors, but
it *is* relevant to engines that can operate with acceptable smoothness
LOP. That rules out most every carb'd engine (although sometimes you get
lucky), and most every big-bore TCM engine. Smaller engines and Lycoming
engines are a "sometimes can and sometimes can't" proposition.

Try it at 65% power and see what happens, especially if you have all-cyl.
monitoring. [I did once have an O-320 engine that would run absolutely
smooth all the way to idle-cutoff. Just a fluke.]
