				Can anyone out there tell me  which way the idle mixture set screw should be turned for leaning the Precision  Airmotive carburetor on my O-320 engine? counterclockwise or clockwise? I'm  assuming there is a standard direction for these carbs. I can't give you a  serial number at the moment, and the meager documentation that came with the  beast isn't explicit on the subject - it just advises to lean until the RPM rise  is 25 to 50 when leaning to cutoff. Thanks for any help on this.
