I have a Mac 300 in good condition, missing the carb, linkages, etc... from the carb box. Otherwise the saw seems complete with b/c, bar scabbard, caps, etc. It shows 130 psi on my gauge and has good spark. If you need parts from this saw or all of it, shoot me a pm. I'm only into it for $20 bucks, so a few bucks over shipping or interesting trade material will be plenty.
You can also email me for a faster response.

edit: If I posted in the wrong forum I can move it to the Swap Meet thread, I just thought this was the right place for a Mac deal.
