s10willy - you are correct about Milwaukee regs having problems.
A few months into running a new one, my bubble flow began to stop throughout the day, everyday. I had to constantly adjust the
needle wheel valve to get it going again. After several hours passed it would stop again and I would repeat adjustments.
I called one of the LFS to try and find a replacement needle wheel valve to see if this was the problem. The LFS said good luck finding one locally because they are not normal stocked items. After explaining the problem the LFS said the reason they are not stocked is because needle wheel valves never go bad and that something else is causing the problem.
I contacted the manufacture, but did not want to send the reg set in and be without CA for an undetermined amount of time.
I took it apart to see if it was clogged and cleaned it. This appeared to help a little, but within a day or so it went right back to having the same problem. After letting this go on for far too long and getting very frustrated with it I finally decided to not accept was I was told about needle wheels never going bad and I bought a new one online. After replacing it the Milwaukee reg has worked great!
