## Discrepancy

DURING ANNUAL INSPECTION, A PRESSURE TEST OF THE ENGINE FUEL SYSTEM REVEALED A LEAK AT THE MIXTURE CONTROL SHAFT WHICH DRIPPED ON THE MUFFLER BELOW .  REPLACEMENT OF O - RINGS 953516-10 AND 951401 CURED THE LEAK.  SUBMITTER SUGGESTED CLOSE INSPECTION AND PRESSURE TESTING SHOULD EASILY FIND THIS PROBLEM.
