prior to applying
takeoff
power.
Even
cautious
power
applications
with cool
oil
may
result
in
momentarily
exceeding
the 39.0 inches
Hg.
manifold pressure
limit.
Refer
to Section 7
if
momentary
overboost
of
manifold
pressure occurs.

If
the
ignition
system
produces
an
engine

drop
in excess
of
150
RPM.
or

the
drop
in
RPM
between

by
more
than
50
RPM,
continue

a
minute
or
two
longer before rechecking
the system.
If
there
is
doubt
concerning operation
of
the ignition system,
checks
at

if
a deficiency
exists.
