## Discrepancy

PILOT REPORTED MIXTURE SETTING CONSISTANCY WAS ERRATIC.  INVESTIGATION INTO THE CONTROL MOUNT IN THE ENGINE COMPARTMENT REVEALED THE U-CHANNEL THAT SUPPORTS THE MIXTURE CONTROL HAD WORN TO AN EXTENT THAT THE CABLE HOUSING WAS SLIDING IN THE MOUNT.  THE OUTER CABLE NEEDS TO BE HELD FAST FOR PROPER OPERATION.  THE BRACKET SUPPORT HOLDS BOTH THE MIXTURE CONTROL AND THE THROTTLE CONTROL, ALTHOUGH THE THROTTLE WAS IN GOOD SHAPE.  THIS BRACKET, PN 0750613-4, WAS REPLACED AT THIS TIME.
