Well since no one has replied yet...... From the cutter I see you have the top plate angle too shallow, not grinding deep enough into the tooth, If all your cutters were sharpened that was which I believe you said. The cutters still are dull the point is still rounded over you did not take enough material away. Actually the chain is sooooo dull I am amazed you can even cut, Maybe that is why there is burn marks on the bar.

close...
Adjust your angle of the motor to about 55 deg. Set your chain angle to about 30 deg. Then adjust your depth to where the rounded part of the stone just clears the edge of the tooth (like a file would).
When fixing a rocked out chain, plan on making several trips around the chain. Better to make small cuts rather than larger ones.
Avoid heating the tooth!!!

to begin, the bar has burn marks because that bar is the one i solely use for cutting stumps...i find alot of rocks in my stumps and that is what happened to the chain. i tried to take as lilttle off as possible to sharpen it back up to be usable.....the angles i am sharpening the cutter to are 25 degs and 60 degs. gonna take some more off the cutters tommorow with a few more passes and will post another pic. those cutters still have a lot more meat on them, but the right-hand cutters seem to have taken most of the damage.

It seems like the right cutters always end up rocked up.... 25 deg will be fine, I think the 60 is a little steep but if it works for you go for it.
