pumped to the carburetor through an external fuel
pump mounted on the console assembly. The carbu-
retion system maintains a fuel reservoir in the float

engine. During carburetor adjustments, DO NOT
FORCE ADJUSTMENT SCREWS INTO SEATS.
• TO ADJUST CARBURETOR - Close the high-
speed jet (DO NOT FORCE). Then open the high-
speed jet (figure 8) to the settings shown on the
carburetor settings chart for your particular
engine (see figure 10).
The high- and low-speed jet adjustment screws for
the Bendix carburetor used on Model SD15P1 OB are
located on top of the carburetor and are identified
as HI and LO.
The engine can be seriously damaged
if
operated with a lean gas mixture (high-
speed jet turned in too far).
