I have a decent little 51 for sale the piston has no scoring it holds 150lbs of comp on my gauge the saw is bone stock it has scratches and scuffs the tank vent dose leak a little it has no striped holes it oils as it should the chain brake works I did put a new fuel line and a wire from the coil to the kill switch. If you are looking for a nice shiny saw this saw is not for you but it will make someone a great little firewood saw. I am asking $115+the ride to your door Thanks' for looking. I am open to reasonable offers
