General information about engine tuning

Difficult starting, insufficient engine power and increased fuel consumption are usually associated with general wear or improper adjustment of engine mechanisms and systems, therefore, the relevant components should be periodically checked and adjusted (see "Maintenance Schedule").

Since the need to adjust the engine may arise at any time, regardless of maintenance, the description of the adjustment work is highlighted in a separate chapter. The sequence of description corresponds to the logical sequence of actions when performing a complete adjustment of the engine.

For troubleshooting, see chapter "Engine stalled or won't start". Ways of rotation of the crankshaft of the engine are described in the chapter "Basic rules for work".
