For correct engine timing the marks on the camshaft sprocket must be
even with the cylinder head mating surface at the same time the "T"
mark is lined up with the with the index notch in the timing inspection
hole. Also the camshaft sprocket mounting boss should be visible above
the cylinder head surface.
If this is not the case, rotate the crankshaft 360° clockwise until the "T"
mark is once again aligned with the notch on the case cover.
