Chainsaw Repair

hi Everyone,

After my adventures learning about chainsaws with the little powermac 310 rebuild (my first chainsaw and first 2 stroke engine) I was at an auction today and rather than buy the newer looking working saw (where is the fun in that!), I bid on and won a Mcculloch Titan 70. Looks like it's got some meat to it and it's a heavy saw. It has a 20" bar on it but the engine will not turn on the starter... it is solid. On a first look it seems someone has had the head off as there are two bolts missing and another is slightly undone there also is what looks like a hose union coming from the back of the head... what is that for there doesn't seem to be hose adrift.

There is a red button on the top of the head... whats it's purpose?

I'll start stripping tomorrow and get some pics up but can those in the know advise what would be terminal signs for the saw. I'll put some penetrating oil into the chamber and see how I go but any other tips for freeing the saw?

Any other info on this saw would be appreciated.

Many thanks
