This reduces repair time and provides an engine with all new internal parts assembled to new engine production standards. All parts being transferred should be thoroughly cleaned of dirt, oil and grease, and carefully inspected to be sure that all parts are suitable for additional service. Additional engine parts necessary for the repair of the old engine should be supplied from parts stock. Any new parts that are required should be ordered from the parts list covering the original engine model − type − code number. In some instances the internal parts in the Short Block differ from those used in the original engine. Therefore, to identify the rebuilt engine for future parts requirements, a metallic self-adhesive label is supplied in an envelope with each Short Block. The label bears a symbol (example V-1) and should be attached to the engine adjacent to the model, type and code numbers that are stamped on the engine identification nameplate. At any time repair parts are ordered, add the symbol to the original type number (example 0134 V110). This will permit identification of the proper parts in the Short Block. To apply the symbol label, first thoroughly clean the area in which it will be applied using petroleum solvent. Carefully peel the backing from the label by starting at one corner. Apply label evenly in position, using finger pressure to smooth out the surface of the label. for SPECIAL INSTRUCTIONS LUBRICATE UPPER CYLINDER: Before installing the cylinderNot head, move piston near top of cylinder bore. Place 2 tablespoons of clean engine oil around outer diameter of piston. Crank slowly to spread the oil. This will protect the upper surfaces of the piston and cylinder bore during the first few momentsReproduction of operation. WARNING: BEFORE STARTING OR RUNNING ENGINE, STATIC ADJUSTMENT OF THE GOVERNOR MUST BE MADE. FAILURE TO MAKE STATIC ADJUSTMENT COULD RESULT IN ENGINE OVERSPEEDING WHICH MAY RESULT IN ENGINE OR EQUIPMENT DAMAGE CAUSING PERSONAL INJURY OR PROPERTY DAMAGE. ALWAYS REFER TO THE APPROPRIATE BRIGGS & STRATTON REPAIR MANUAL FOR PROPER STATIC GOVERNOR ADJUSTMENTS. BRIGGS & STRATTON CORP. Milwaukee, Wisconsin 53201.
