## Discrepancy

(CAN) CRACKED EXHAUST STACK FROM CYLINDER NR 3 MELTED THE CARB HEAT CABLE INTERIOR LINING CAUSING THE CABLE TO BE VERY STIFF. CABLE.  CRACK LOCATED INSIDE THE CARB HEAT SHROUD AT THE MOST FORWARD POINT WHICH IS VERY DIFFICULT TO INSPECT. RECOMMEND REMOVE SHROUD PERIODICALLY FOR BETTER INSPECTION. EXHAUST STACK WALL EROSION IS DIFFICULT TO DETECT.
