Just wrapping up restoring the first of my dad's old chainsaws, the big Echo, and about to start on the little McCulloch. I haven't seen any model/serial numbers yet, probably still covered in grime, but it says "McCulloch 2.0 CID" on top and "Eager Beaver" on the side. Both were from the early '80s. Any chance someone recognizes it and can point me to any manuals, parts diagrams, anything? Thanks
