So, I checked before replying. The Base Control Valve is at "3 clicks out" from full clockwise. Recommended setting is "8 clicks out" from full CW. The High Speed Valve and Sweep Control Value are at factory setting. I'm guessing this is not optimal for the conditions I'm describing? Nope too stiff on the low speed. Try it at the factory 8 clicks, it'll work better and you'll be less tired.
