The carburetor was disassembled. The screen filter was found clean. The floats were found detached from the lever arm assembly and were found in the carburetor bowl bottom along with drops of metal similar in the color and the consistency of lead. The rubber valve tip was found pliable and no deformations were observed. The lever arm's tab was found worn in the spot where it contacts the valve. A black fibrous material was found in the venturi area. The float level was checked with a 13/64-inch go/no-go gauge and was found high. The attached Stratoflex fuel hose was inspected. The hose was marked MS28741 8 0144 and 1Q77. The hose was stiff when flexed. The hose was pressurized with fluid to 30 psi and did not exhibit any leaks. Cessna service letter SE71-7, dated April 5, 1971, states: RECOMMENDED INSPECTION & MAINTENANCE PROCEDURES - FLEXIBLE FLUID HOSES 5. Flexible hoses which are found leaking or showing a notable amount of stiffness are to be replaced. It is suggested that all flexible fluid carrying hoses in the engine compartment be replaced at engine overhaul or every five years, whichever comes first.
