Has anyone encountered a problem with filing cheap chains from china? About a week a go my 28inch Holtzforma bar and chain turned up, went great all day on the factory sharpen, but at the end of the day when i went to give the chain a tickle up i noticed some teeth filed normally but some were ultra hard and i couldnt grind any meat off, my file just slid on the tooth and it made a totally different sound, any way, i progressed to sharpen all teeth with even amounts of strokes, but some teeth filed better than others. End result is horrible cuts with the bar drifting off fairly quickly. Im thinking on just chucking it out but would love to get it sharp like the factory did. My bar rails are even with no wear, and teeth sizes are fairly identicle as its only had one sharpen with even amount of stokes, so the bizzare drifting has me baffled. The chain cut big rata and pine all day on the factory sharpen. If someone could give some insight that would be so greatly appreciated
