I lost the double action capabilty like it was set to be full on and wide open. Though I had to tear into it dispite warenty issues from Testers not to do so like it's some kinda state secret.
Turned out that the steel shaft that pushes into the needle assembly was pushed waaaaaaay to far back. Into that red dingus part thingy. Thus the needle stays back and with wide open paint flow. Pulled it forward and reassembled it...works just fine!
Now totally convinced that I can fix a rainy day.

Is there a FAQ on troubleshooting this thing?
