(7) Check action of impulse coupling (D-2000 series only). With the ignition switch off observe
breaker cam end of rotor while manually cranking engine through a firing sequence. Rotor should
alternately stop and then (with an audible snap) be rotated rapidly through a retard firing position.
d. Generator or Alternator Output –
The generator or alternator (whichever is applicable) should be
checked to determine that the specified voltage and current are being obtained.
2. FUEL SYSTEM.
a. Repair of Fuel Leaks –
In the event a line or fitting in the fuel system is replaced, only a fuel soluble
lubricant, such as clean engine oil or Loctite Hydraulic Sealant may be used. Do not use any other
form of thread compound.
b. Fuel Injector Inlet Screen Assembly –
Remove the assembly and check the screen for distortion or
openings in the strainer. Replace for either of this conditions. Clean screen assembly in solvent and
dry with compressed air. To install the screen assembly, place the gasket on the screen assembly and
install the assembly in the throttle body and tighten to 60-70 in.-lbs. torque.
c. Fuel Grades and Limitations –
See recommended fuel grades in Section 3.
In the event that the specified fuel is not available at some locations, it is permissible to use higher
octane fuel. Fuel of a lower octane than specified is not to be used. Under no circumstances should
automotive fuel be used (regardless of octane rating).
NOTE
It is recommended that personnel be familiar with the latest revision of Service Instruction
No. 1070 regarding specified fuel for Lycoming engines.
d. Air Intake Ducts and Filter –
Check all air intake ducts for dirt or restrictions. Inspect and service air
filters as instructed in th
e airframe manufacturers handbook.
e. Idle Speed and Mixture Adjustment –
(1) Start engine and warm-up in the usual manner until oil and cylinder head temperatures are
normal.
(2) Check magnetos. If the mag-drop is
normal, proceed with idle adjustment.
(3) Set throttle stop screw so that the engine idles at the airframe manufact
urers recommended idling
RPM. If the RPM changes appreciably after making idle mixture adjustment during the
succeeding steps, readjust the idle speed to the desired RPM.
(4) When the idling speed has been stabilized, move the cockpit mixture control lever with a smooth,
steady pull toward the Idle Cut-Off position and observe the tachometer for any change during
the leaning process. Caution must
be exercised to return the mixture control to the Full Rich
position before the RPM can drop to a point where the engine cuts out. An increase of more than
50 RPM while leaning out indicates an excessively
rich idle mixture. An immediate decrease in
RPM (if not preceded by a momentary increase) indicates the idle mixture is too lean.
