The 25-50 RPM rise should be seen at sea level.  What's your home airport elevation?

(I prefer to have it on the lean side.)

My IO360 idles smoothly at 760-780RPM.
I've been told that the correct mixture setting at idle has been achieved when pulling mixture to full lean
results in a 25-50RPM increase before the engine quits. Is this what I should be looking for?
I don't see it yet so I'm thinking I should richen up the mixture a click or two until I see the rise.
What do our resident engine experts say?
