Hi guys. I had written a few posts regarding a Stihl 038AV I was planning to rebuild. Well I am glad to say that I am almost done and the saw should be running by this weekend. I have a few questions however. I have two brand new air filters that I found that I can use. One has a screen element and the other is a screen with some kind of fuzzy material on it. Does it matter which one I use or not? Also, an old man gave me a box of old solid tip (no sprocket) bars that are made for the 038. Since I got them free, should I use these bars or are they junk and don't last? Thank you.
