First time posting. I am a firewood guy. My first (and only) saw was a 450 rancher. Bought it in 2012 and have cut about 50 cords with it. Have always run 50:1 ethanol free and generally taken care of it. Stopped oiling this spring and a new oiler was only $50 (parts and labor) at the saw shop. Now it has a different problem. Oil pours out (from the correct place on the saw) as fast as I can pour it in. Not sure if I will try to tackle this myself or go back to the shop. In fairness to the shop I have cut 3 cords or so since the repair, so i am not blaming their work. My larger question is what is considered "high miles" for this saw. I don't mind a little maintenance, but if its time to bite the bullet (and get that 50cc pro saw) I would like to know. Is there a rule of thumb for normal life? Thanks in advance.
