Hi guys, I found this forum looking for an answer to my problem. Thanks to anyone who lend a hand.
I have a few year old MS 170. I am a very occasional user, who is still on my first quart of bar oil. I had noticed that the chain was running very hot. I noticed some bluing on the bar. I cleaned everything, and bought a new Stihl chain (14" bar)....ran the saw the other day, same thing, obviously not getting any lubrication. Took the bar off today, all is clean, all holes look good. I read a couple of columns, but really do not know where to start.
Like I said, this saw is still on its first quart of Stihl chain oil, nothing else has been used. I removed the rubber from the handle, and removed the oil hose from the bottom of the saw. I used low air pressure to push out toward the filter (in case there was a blockage). All the oil came out of the tank clean, 2-3 small chips.. I have tried to blow "up" the metal orifice in the bottom of the saw, nothing came out, and it did not feel as though air was going in. I tried to blow air in the oil exit hole near the bar....nothing there either. Put it back together, re-ran (without the bar) and still nothing. I do have torx bits, and most every tool (except for specialty Stihl tools). I just don;t know where to start. From a most probable problem...to least probable. I don't want to tear this thing apart, if all I need is a hose or something.
Sorry for the long post. Thank you for any advice!
Joe
