Saw runs and oils as it should. I just don't use it as much as I thought I would. When I bought it a couple years ago, I replace fuel and air filters and changed to 3/8 x 7 pin sprocket just to match the rest of my saws. I've been running it with a Tsumura Light and Tough bar, 3/8 x 0.063 x 60 dl. $225 PHO or $300 package deal with the Tsumura bar and 3 chains. Pick up or buyer pays shipping from 17078. Or, I could bring it to the PA GTG on June 10, 11, 12 to save on shipping.
