Well, I have six of them so far. Parts are out there, so are other forums that cater to the MTD 990 series. When I can, I will start restoration processes on some of them. When you find one, try to buy it. Evaluate the purchase for your own needs (parts) and you can always sell off what you don't need to someone who needs a part. Currently just using my runners as is. Time to set up for snow plowing is approaching. Us 990 fans here in Michigan are pretty close in contact when trouble occurs to one of our machines.
