System holds 27in Hg of vacuum after 30 min.of evacuation and In trying to recharge low and hi side pressure are 60psi low & 120psi hi when compressor is engaged & 90psi low & 70 hi when not, Line going to evaporator is warm when compressor is not engaged and cool when is it possible that orifice is plugged also causing back pressure @ hi side service port?
