Ok, here's what's going on with the 075:
I bought the saw for $247.60 on eBay a year ago. I thought it was a deal. It was listed as used with good compression. I immediately milled some wood with it. That was last summer. But the saw seemed to be running hot and was dieseling. I couldn't get it to idle properly. Here it is making the first cut I made with the saw:
I took it into the local Stihl repair shop where I sort of know the mechanic. He was a school shop teacher and then was trained as an aircraft mechanic, so overall I fell he's pretty decent. He pretty quickly ascertained that the crank seals were probably leaking, causing it to run lean and therefore hot. So he replaced those. He also noted that the oiler gear was worn out, so we replaced that as well. I bought an aftermarket part for that but it wouldn't quite fit. I think he ended up ordering an OEM part for it (at least, that's what I recall seeing on the bill and it was about 80 bucks, which fits with what I would expect it to cost).
So, tuning, seals, new oil worm gear etc. probably ran me about $150-$250. The saw ended up living there for several months, but I wasn't in a huge hurry. I got the saw out of the shop right around new year's day. It started right up and ran great, and that's when I milled more of the walnut that you will see in the pictures below. (Note - I still couldn't get it to idle correctly, but that may be my own lack of experience - not sure).
I milled some hickory with it in February, and cut down this oak tree (
http://www.arboristsite.com/community/threads/biggest-tree-ive-ever-cut-down.253350/) with it about 6 weeks ago. However, I couldn't keep the saw idling properly again. I was also getting sick (I figured that out later - just read the thread if you want to know more) and, to make a long story short, I probably shouldn't have been cutting that tree with that saw when I was in that condition. However, the tree went right where I was trying to put it and nobody got hurt, so I am counting it as a win.
But, it led me to decide that I needed to either make the saw REALLY run properly or get a different saw, because as much as I love this hobby, it's not worth dying for. So, I sat down a month ago to look through the saw. At that point, I really decided that the person who sold it to me /should/ have listed it as a parts saw. Even though it runs, has good compression, etc., it's just had a bunch of Mickey Mouse stuff done to it in it's life. It is not really terribly close to original.
I am telling you all of this because even though I want to sell it and buy an 084, I don't want to sell you a pig in a poke. I enjoy this community and I value my reputation here. I want you to have all the information before purchasing, including that I am probably not qualified to give you a really strong opinion about the shape that the saw is in. I am working toward that, but am not there yet.
Lastly, I also recently bought a full wrap handle including the hard to find connector piece that allows you to actually attach it to the saw. I can post a picture of that if you are interested. I paid $40 plus shipping for it and would add it to the deal for that same price or you can make an offer for the whole package.
I don't really expect to get the $400-$500 I have in it back out of it, but I am willing to take some loss in exchange for the experience and investment that I needed to make to be sure I wanted to keep milling (I do). So I want you to know everything I can tell you and have taken a bunch of pictures and would consider serious, fair offers. I would also love any advice the community at large is willing to issue about what the saw is likely worth.
There, now that I've written my novel, you are free to decide what you want to do. This is by no means a pristine saw. However, it does run, cut wood, etc. You can see/hear it operating in the video I posted. It has had some of the work done to it that it needs, but someone better than I am at this should really go through the whole thing were they to keep it or part it out to keep some other saws running else.
Pictures below. I am happy to answer questions.
