According to service manual close the bleed screw, I hadn't read that in the operators manual only in the 1850-1950 about the bleed screw in the service manual. I only have changed the settings on the bypass? I don't remember ever backing out the bled screw. Do you need to know the location of the screw I can post a picture. I have to wait till I get done with hay just in case I mess up about a month.
Thanks Darryl
