Seem to be a lot of purely opinion based threads about lately so I thought this might be good for a change. I picked up an alleged 076 parts saw some weeks ago so I decided to do some research on the development/differences of the series. I have read nearly all the 050/051/075/076 threads I can find using the search function and Google, using keywords such as "075 trigger", "051 ignition" etc I can tell you it makes one hell of a difference if someone has used an appropriate title. I have a service manual (seems to have quite a few what i interpret to be ambiguous statements). I have been looking for 1978-1980 ipls for the 075/076 saws (which are my primary interest), there are some on ebay US but one of the sellers blocks international buyers from contact and the other I haven't heard back from. Tech update (27.1980) seems to be the "missing link" but again I have come up with nothing. :help: From what I have read there seems to be one hell of a lot of heresay and contradiction surrounding the saws (quite a lot from Stihl themselves). In the past several AS members have testified that they have owned a 075 with a side oil cap but for the most part they have been ignored... There are going to be quite a lot of pictures some of which I have borrowed from fellow AS members so I hope no one minds.
