Here is a photo of the adjusting knob that I could find inside the machine. It isn't easy to see straight on. I can look at it from the side. There is an arrow on the front of the dial, but no exact numbers to adjust the knob to. Any advise on how much to turn the knob?
Shawnette, I have been giving some thought lately to putting together one of those holding tanks that Trey was so kind to share his instructions to.
