CARBURETOR-MODEL 5811
IT IS IMPORTANT NOT TO FORCE ADJUSTMENTS
INTO SEATS.
The dual carburetors used are Tillot-
son
Model HL-209 and HL 210 Carburetors. For best
results
the engine
should
be warm when final carbu-
retor
adjustments are made. Figure 18 shows the left
side
of
the
carburetor,
and Figure 19 shows the right
side.

.
STARTING
.
A COLD
ENGINE-Close choke and
cra
nk
engine.
After the
engine
starts move the choke to
the
open
position. Do not move the throttle lever far
enough
for bottom carburetor to be open. The choke
is on
the top carburetor only, and any opening at the
bottom will cause fuel
starvation
and hard starting.
2.
STARTING
A WARM ENGINE -
It should be
started with the
choke open.
The
choke
is shown in
Figure
18.
3.
TO ADJUST CARBURETOR -
Turn in the high
speed jet on the bottom
carburetor
all the way
(DO
NOT FORCE),
then open 1
1/4
turns as shown in Figure
18. When engine is warm place unit on the kickstand
and slowly
accelerate to high speed. Turn high speed
adjustment
needle in to the point where the engine runs
the fastest
and smoothest, then open needle (turn out
1/4
turn).
Turn
in the idle mixture screw all the way
(DO
NOT FORCE).
Open 1
full
turn as shown in Figure
19.
IMPORTANT: MAKE NO OTHER ADJUSTMENT OF
IDLE
MIXTURE SCREW.
This
adjustment controls the
mixture
at idling
speeds.
A lean idle mixture will
cause
poor acceleration. Adjust the idle
speed
screw
shown in Figure 18.
Keep idle speed slower than
clutch engaging speed
(approximately 1750-2000 RPM).
NOTE:
Figure 18 also
shows
a throttle wire adjust-
