Went flying yesterday and tried LOP again in my Bulldog
(Lycoming IO-360, standard FIs). Seemed to work ok.
Needed a fair bit higher MP to maintain the speed, but the
CHT (only one) was much lower than "normal". However
one thing I found was that the fuel burn for the same speed
didn't seem any lower, and was possibly a bit higher than
what I normally fly. I fly on pretty low power anyway usually
so I lean until the power starts reducing then bring it back a
shade. Probably the max-power setting, though only at about
50% power or so.

I, too, have a Lycoming IO360 with standard FI's.

If I lean relatively slowly, I find that my airspeed doesn't drop off until
I am 25-50° LOP. If I then enrichen a bit, I'm still LOP.

If I lean very, very slowly, I will see the airspeed drop off sooner.

Could it be that your "normal" procedure leads to LOP settings?
