ADJUSTMENT
The

be
checked
while
the
airplane
is
in
flight.
Observe
the
takeoff
rpm
to
see
if
it
exceeds
the
redline
figure.
If excessive
rpm
is
observed,
land the
airplane
and
adjust
the
high
rpm
screw
inward to
reduce
the
rpm
to
the
redrine
figure.
The
high
rpm
adjustment
screw
is
located
at
the
front
of
the
governor
just
forward
of
the
speed adjusting
control lever.
One
complete
revolution of
the
screw
reduces
the

by
approximately
25
30
revolutions.

bring
the
propeller
back
to

the end of
the
governor
control
shaft
inward
