I ordered and received from Sears a cylinder head and head gasket for my old (1979) Craftsman lawn mower. The mower is model number 131.907223. Its engine number is 143.294112. The cylinder head I've received is Tecumseh part number 00036474. I need to know the proper torque settings for the eight cylinder head bolts and also for the spark plug.
All Tecumseh 2-cylce engines with type numbers starting with numbers (Outboard engines, rotarty mower engines, chore engines). These engines are 8 HP and less. Excludes TVS840 TVS850 and Snow-King (HSK) 2-Cycles and the TC series. 25 90 45 (aluminum rod) 75 (steel rod) HH 80-150 50-55 180-240 86-110: OH 120-180 50-55 180-240
