Learn how to quickly get best power during the takeoff roll, using
your mixture control for any higher altitude takeoffs[...]
Some use a full power runup to adjust for
max RPM before starting the roll but I always hesitated to do that to
an engine just before takeoff.

There's a good reason for doing it BEFORE starting your takeoff roll, and
frankly, adding "fiddling with the mixture" to the things a pilot has to
deal with DURING the takeoff roll seems unwise to me. Never mind the fact
that once the airplane is moving, you will have a much harder time
identifying the point at which the engine is developing maximum power, since
RPM will be increasing as the airplane accelerates.

I have no idea why you'd hesitate to do something proven to be safe, and
which is much less hazardous than your personal procedure, but I hope that
no one else applies your advice to their flights.

Having an EGT gage really helps. I think it should be mandatory on
any carburated engine but that is just the engineer in me showing I
guess....

The EGT gauge is not necessary, nor useful, for the purpose of obtaining
maximum power for takeoff. Your RPM gauge will give you a 100% reliable
indication of maximum power, since maximum power will result in maximum RPM
every time. Using the EGT gauge adds an additional layer of indirection,
and you may or may not wind up with the actual maximum power mixture setting
using it.
