Adjust the idle r.p.m., and verify that, at higher power settings, leaning
the mixture control produces a rise in exhaust gas temperature;
otherwise, the mixture is too lean. Make sure there is a slight rise in
r.p.m. when the mixture control is moved to the idle cut-off position.
After each engine run, check every system very closely and remedy
defects if necessary. Check all wiring, hose ducting, fuel and oil lines,
etc., for excessive vibration or chafing. Make sure all plumbing and
wiring is securely fastened with nylon ties, hose clamps or the like.
Check the full-power engine operation before flight is attempted.
Perform the full-power checks with the engine cowling and spinner
installed. Point the airplane into the wind to assist engine cooling. Tie
the airplane down securely and chock the wheels for the full-power
tests. Verify that the engine runs smoothly and strongly at full power.
CAUTION
Hold the stick in the full aft position during the full-power tests.
If the stick is allowed to go forward, the tail could rise, possibly
resulting in a prop strike and serious engine damage.
If your airplane has a new, remanufactured or overhauled engine, it
should receive the same start, warm-up and preflight checks as any
other engine. Using low power settings for cruise during the break-in
period is
not
recommended. A good engine break-in requires that the
oil film that lubricates the piston rings and cylinder wall break down
slightly and allow some wear to occur. This wear, or “seating,” of the
