The following illustration shows the part of the
carburetor which begins and stops to function at
different throttle slide openings.
Note that the wider part of symbol corresponds to
the opening mostly affected. For instance, throt-
tle slide cut-away begins to function at closed po-
sition but it is most effective at 1/4 opening and
decreases up to 1/2 opening.

NOTE : For fine tuning refer to TECHNICAL
DATA 09 and to SPARK PLUG 05-03.
NOTE : For high altitude regions, the High
Altitude Technical Data Booklet (P / N 484
0648 00 and 484 0545 00 for binder) gives infor-
mation about calibration according to altitude and
temperature.
INSTALLATION
CAUTION : Never allow throttle slide(s) to
snap shut.
To install carburetor on engine, inverse removal
procedure.
However, pay attention to the following :
– Inspect throttle cable and housing prior to in-
stallation.
On applicable models, make sure to align tab of
carburetor and air intake silencer (if applicable)
with notch of adaptor(s). On applicable models, in-
stall adaptor with up mark facing up.
CAUTION : The rubber flange must be
checked for cracks and/or damage. At as-
sembly, the flange must be perfectly matched
with the air intake manifold or severe engine
damage will occur.
Install clamps in a way that their tightening bolts
are staggered — not aligned.
Hook throttle cable into the needle retainer plate.
NOTE : Do not obstruct hole in throttle slide
when installing needle retaining plate. This is
important to allow air escaping through and thus
allowing a quick response.
