I have a problem with my 3 point adjustment knob. Basically it does nothing. It will not slow down or speed up when lowering 3 point. I already changed seals.
Does it turn really easy? The knob may need tightened on the shaft (flow control needle). I think there is a center nut or screw that may have worked loose on the adjustment knob. Do you need it to go faster or slower? If you need to make it go slower, you can make a quick temporary adjustment by loosening the big nut at the cover plate about 1/4 to 1/2 turn and then turn the knob clockwise until you get resistance and then try a little more pressure on the turn to get it to go another small amount to slow the flow. If that works be sure to retighten the big nut at the cover plate.
