My 350 husqvarna chainsaw, 52cc, 4hvxs.0525aa has scored jug, piston and rings. To repair $200 to $250. I've chosen to buy new chainsaw, since I have nearly new chains and bars for the 350. Husqvarna doesn't make a 350 anymore. What will interchange with my existing good parts. Chain is 3/16, .050 gauge, .325 pitch. A couple choices would be great.
