PILOT
SYSTEM The Pilot
System
is comprised
of two adjustable
components:
PILOI AR
SCREW
when turned in, richens
the fuel mixture by reduc-
ing
the
air
flow into
the
Pilot
System which operates from idle to approxi-
mately
1/4th
open throttle. The effective adjustment range
of
the Pilot
Air
Screw is between
1ä
to 2 turns out. lf the Pilot Air
Screw needs
to
be
set
more
than
2 turns
out
to
achieve
the
best
idle, the
next smaller size Pilot
Jet
is required.
lf less than
1ä
turn
is required,
then
a
larger Pilot
Jet
should
be
used. The Pilot Air
Screw should
be
adjusted
to
provide
the highest
engine
RPM
while the engine
is
at
idle.
PILOr
JET is the component supplying the majority of fuel from idle
to
1/ath
throttle
position.
The
typical
jet
size
should fall between No.
15 and
No.30. For selecting the
correct
Pilot
Jet at
idle,
read the
previous
tuning
directions
tor
the Pilol
Air
Screw.
ll
the engine
appears
to run
too
lean
or too
rich
off of
idle,
the carburetcir may
require
a size
smaller or
larger Pilot
Jet
and/or
the
Pilot
Air Screw may
require
adjustment.
