Those Poulan 3700's with the two thin rings usually run about 150 psi and then with a deleted base gasket you should get at least 150 to 155psi. 

That cylinder sounds pretty worn if some of the plating is gone.    After putting on your new rings if the compression is still low I would consider another cylinder.
