"Small", apparently neglectable causes are often responsible for a "big" effect, i.e. disturbance
of engine operation. Detection of the causes is not always easy. The hints to possible trouble
causes and their correction contained in this section serve as a guideline for the engine user, listing
the most frequent faults. This list of causes, however, does not claim for completeness.
Repair work must be done only by persons authorized to perform the specific task.
