I suggest you read through some of Deakin's articles on www.avweb.com to

Yes, I have been reading many great articles on avweb. Unfortunately, my
152 does not have EGT or CHT monitors, so I have to use the "listen, learn,
and pray" method of leaning. I find it mentally difficult to reach over and
start easing the mixture back with the throttle full forward.
