Husqvarna 2100 CD 2100CD Chainsaw Powerhead with full wrap handle. Ships free here in the US.

The saw has very good compression and runs good and strong. Starts with 2 stroke poured down the carb and idles and runs fine after that. 

It's missing a few parts so I have it listed for parts or repair. 

As far as I can tell it's missing:
Upper bolt on the dog spike
Clutch bearing 
Chain guides
Clutch cover
Choke pull
Ignition kill switch
Air box and cover
