Just found at a local estate sale.  This is a POULAN PRO 35CC PP3516AVX chain saw with 16" bar. Unknown running condition.  It is not locked up.  Throttle is not frozen up but does feel a little stiff.  This is sold for parts, or might need repaired.  I am sure it probably could use new fuel, maybe a carb cleaned.  Check out the pics good and make sure this is exactly what you need before you buy it.  This is sold as is, all sales are final.  No returns. Thanks
