Hi! I have an MS 660 for sale. Maybe clutch cover is aftermarket, but other parts are OEM. I tried to start this saw but after second pull I tore the starter rope. I got this saw through the post and I was told it is a great runner. Gas and oil tank were filled, chain and dust cover were oily, so even though I tore starter rope and I could not test this saw, I think we can assume that this saw has been started recently. Chain brake works. I'm asking $525 shipped PHO. I accept PayPal. Shipping with FedEx, tracking included.
