2.
Lack of power.
Step 1.
Check for improper engine adjustments and gear train timing.
Perform adjustments in paragraphs 3-9, 3-10, 3-31, 3-33, and 3-36, if performance is not
satisfactory.
Check the engine gear train timing. An improperly timed gear train will result in a loss of
power due to the valves and injectors being actuated at the wrong time in the engine's
operating cycle. Refer to paragraph 3-33.
Step 2.
Check for insufficient fuel.
Perform a Fuel Flow Test and, if less than 0.8 gallons per minute with engine at 1200 RPM,
consult the No Fuel or Insufficient Fuel Table 3-4.
