CARBURETOR
ADJUSTMENT
7.
Your carburetor has had approximate settings made
on
it
at
the
factory, however, altitude and
temperature
differences may necessitate changes.
Your dealer should have made these adjustments
in
his pre-delivery service
of
your machine.
No. I
is
the idle mixture screw. Approximately 1
Y2
turns
open
is
the
recommended initial setting. Poor
acceleration may indicate improper setting.
No. 2 is the high speed mixture screw. Recommended
initial setting
is
from
I
~
to
I
Y1
turns open.
Too
lean
setting will lead
to
engine over-heating and possible
failure.
Too
rich a setting will cause excess exhaust
smoke, "four-cycling" and plug fouling.
Just
at
the
point
of
eliminating
the
"four-cycling" effect
at
full
throttle
is
the
correct setting. Only under full
operating load can tests
of
setting be made.
No. 3
is
the
idle speed setting. This should be
adjusted after the idle mixture screw
is
set
to
a speed
below clutch engagement. Spring loaded
adjustment
screw is on
the
opposite side
of
carburetor.
CAUTION
Do
not
adjust
any
part
of
carburetor while
engine is running.
Note:
If
in
doubt
about
any setting, contact your
dealer.
