Growing up I helped my father cut wood for a living. I always admired his affinity for the forest..... and his chainsaws. He was picky about what he ran. Only professional models 046 and up and a few 372 xps. Six months ago I bought my first pro grade saw a fine 046 magnum. I have bought several new Sthil RSF chains and equipped my saw with a powermatch es bar. I love my saw and it cuts like a dream. But....... after installing a new chain guide plate it seems that my chain rubs against it. This had created a flat wearing on all of two chains drive links and scarring on the plate. Any suggestions?
