## Discrepancy

FULL THROTTLE STOP WORN CAUSING A LEAN MIXTURE.  WHEN THE PART IS FULL RICH WITH THE SCREW TYPE MIX CONTROL, PRESSURE IS PUT ON THE FULL RICH STOP.  STOP IS BEHIND A COVER PLATE WHICH HAMPERS VISABILITY.  WEAR CAUSES THE METER HOLE ON MIXTURE TO OVER-CENTER CAUSING A MORE LEAN MIXTURE.
