I Inherited a bunch of Stihl bars and chains last week, and looking over the bars, I noticed that one of them had a burr groove worn down on both sides of the bar about two inches back from the tip. I usually associate burr grooves with someone using a dull chain and leaning on the dogs, but this was near the tip. Could it be from an over-tightened chain?
