Rusty,
I wish I could help you with the saw but we never have tried to start the one we have. Got to thinking about things you might want to check out however. We have and old Mercury outboard engine made somewhere in the 50's. Grandad bought it new and we used it off and on fishing. about 15 years ago we went to the lake and couldn't get the thing to fire. After a lot of searching we finally found a coil for it that a longtime dealer had laying around.
I'm taking a long time telling you to make sure it has fire-----old mags and coils are often fine but if it isn't you would likely have a hard time finding another.
You might also want to pack the thing around a little to see if you want to mess with it--------those suckers weigh a ton

You might want to look up an old 'chainsaw' thread titled 'Mercury Diston saw' if I remember corectly.
Welcome by the way and good luck
Noble
