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
