Installation and Ignition

To locate the firing position of No. 1 piston, first remove No. 1 spark plug and turn the engine until No. 1 piston is moving up on the compression stroke. Turn the engine slowly until the 5° before top center mark on the flywheel is in the center of the timing hole or, on later four cylinder engines, the 5° before top center mark on the timing gear cover is in alignment with the mark on the crankshaft pulley. (I-13, p131)
