Added a 42" bar and two chains (Woodland Pro, aka Carlton, full skip, semi-chisel, 135 dl) for <$200 total. Hope to use these for milling in the future. Also added a Maxflow air filter system. The stock HD2 was leaking fines like crazy! I don't think the stock filter works very well with the 1/4 turn fastener. The HD2 works much better with my MS261 and MS461 where it is tightened with a regular screw-in system. Anyways, looking forward to the PA GTG in June. Hoping to get the saw out to Scott Kunz and back before then. We shall see.
