Wanting to sell this 066AV Power head only. All OEM on rebuild with lots of new parts. Had it in some large Doug fir and it performed great. If you want a list of all the new parts pm me. I also have some video of the saw but will need your cellphone number so I can send you the links. Everything works as it should. Saw was professionally ported when I bought it. Piston pics i can send via picture text. Asking $650 + shipping.
