What was found
DURING AN OIL CHANGE AND ENGINE CHECK, FOUND THAT ON THE LEFT MUFFLER, THE DATA PLATE TACK WELDS HAD FAILED AND THE DATA PLATE ITSELF WAS LOCATED INSIDE THE CABIN HEAT SCAT HOSE. IF THIS DATA PLATE HAD COME LOOSE ON THE RIGHT MUFFLER, IT VERY LIKELY MIGHT BE INJESTED INTO THE CARBURETOR WHEN CARBURETOR HEAT WAS SELECTED.
