POA valve test?

[kna4977]

Wanting to test the POA valve. I have the line off the expansion valve. Is it mandatory to disconnect the line from the back of the POA valve or if so is there another place I can disconnect a line to check it? I can’t seem to get it loose there and don’t want to break anything.

Saw that thread thanks. I got it and tested it. It’s still at 30 which is good for R12 but not 134. Watched a couple of videos but they don’t say which way to turn the nut so which way do I turn the 7/32 adjusting nut inside to lower it down to 26-27? Counterclockwise maybe 1/4 turn? Is there a 3/8 locknut as well?

Has anyone attempted to use a thermostat switch to monitor the evaporator temp and cycle the A6 compressor to avoid freezing? Is cycling a A6 advisable? Looks like Original Air is not rebuilding POA valves anymore and now offering valve and a Thermostat switch. I was under the impression cycling a A6 was not a good idea.
