Unfortunately no pics are possible. Dropped the camera on the garage floor last week and it's slightly dead.

I have done some searching online this morning though and from what I can tell this was a Sears chainsaw from the early '80's and it should have been made by Poulan. I couldn't find any pics of the actual engine but I saw a few cases that looked real close.

I'll see about borrowing a camera to get you all some more details but I'm getting more confident that it is a Poulan so I'm going to look in that area for reed valves and intake parts to see if I can find anything that looks like it'll fit.
