OK temp then. That would tend to increase the the pressure. The too small suction would not allow enough refrigerant for cooling the compressor. Or that was the case the 2 times I have seen it in the last 40 or so years. Aren't sure if the 3 ft of 5/8 I stuck at the end of the 7/8 did any good or not, but the compressor has over 10 years on it.
