Good used OEM Stihl 066 chainsaw powerhead. Used by a pro faller on the West coast, fixed and repaired as needed with OEM parts. Strong compression, fires up in a couple pulls, idles great, good working oil pump and chainbrake for safety.
Lots of scrapes and scratches but solid saw. It WAS an Arctic model, no longer heating now. Handle slightly bent, likely can be bent back, but only slightly out.
