I have been guilty in the past of getting far too excited with the rakers and this has been on some pretty powerful, ported saws too.
If you ever have to start doing more technical felling cuts or bore cuts you'll look like a complete idiot when the saw bites, kicks, stalls etc etc.
I got to the point where enough was enough and I was getting too much bogging and stalling when felling. In my opinion you can take a chain "slightly" past a File-O-Plate setting but any more than that and the chain will only be good for cross cutting small bits of wood.
I did a forestry course a while back thinking all was good until I tried to do a felling bore cut in pine. It bit, bucked, and carried on and the instructor was straight onto me saying that I'd taken my rakers down too far, it was dangerous, and unproductive. He knew EXACTLY what I'd done and was right
