Rakers or "depth gauges" are there for a reason. Chain saw manufacturers have engineers with years of experience who test and design these things. And they of course want theirs saws to cut as fast as possible, but as SAFELY and fast as possible!
With that said, you can buy a "depth gauge' tool like the following which is .25 and is factory spec...
Bailey's - Oregon Depth Gauge Tool
You place that on your chain and the lower portion over a raker. If you can feel the raker sticking up a bit, then you can file each raker down a bit. Maybe try two or three swipes with a flat file on all the rakers. Then check with the depth gauge tool again.
All the rakers need to be the same height, so always file all of them and file each the same number of swipes. Then they are all taken down the same amount.
And the thing is, .25 is pretty high and does not allow much of a cut, HOWEVER this height might be perfect for a harder wood like oak!
I can file them a bit lower for a softer wood, but then if I use that saw for a hard wood like oak, it can become almost uncontrollable! (Saw goes wild!)
Anyway .25 is a good starting point. But don't get very far away from that and only for softer woods.
They sell these depth gauge tools at chainsaw shops as well as online.
