Hi all, I just received a used Milwaukee ma957 w/solenoid. Followed the instructions I found online and set it up. I am having trouble with no bubbles coming out when the solenoid cuts on in the morning. If I adjust it so that I get bubbles, then they won't stop coming out when solenoid cuts off. I have had (1) day where everything was ok. Cut on/off as supposed to and was happy. That was yesterday. And now today no bubbles this morning again. Short version of what I am doing:Open regulator knob valve fully, open main tank valve fully, plug in solenoid, open needle valve, close regulator knob to approx. 10lb., unplug solenoid, attach tubing, plug in solenoid, and adjust. Seems simple enough. As I am adjusting I can unplug the solenoid and the bubbles stop. Plug it in and they start again. Come in the next morning after they were supposed to be on for an hour. Nothing. I have almost had enough already.
