Seats should be positioned for best comfort and visibility. Be sure that
the seats are securely latched in the tracks. Fasten seat belts and harnesses.

levers through their full travel to ensure that they operate smoothly. Set the
parking brake; check that the carburetor heat control is fully OFF; and set
the fuel selector lever to the desired tank position.
4.13 STARTING ENGINE
(a) Starting Engine When Cold
Prime using two to four strokes for starts when the temperature
is +40° F. Use more primer strokes for colder temperatures. On the
last priming stroke, leave the primer in the out position. Throttle
should be set 1/2 inch open. Turn ON the master switch and the
electric fuel pump. Move the mixture control to full RICH and
engage the starter by rotating the magneto switch clockwise. When
the engine fires, release the magneto switch, and push the primer in
slowly to keep engine running. Advance the throttle slightly and lock
primer.
NOTE
This engine does not have an accelerator pump
in the carburetor; thus, pumping the throttle
will not aid in starting.
If the engine does not fire within ten seconds, disengage the
starter, wait thirty seconds, and repeat the starting procedure.
(b) Starting Engine When Hot
Close the throttle. Turn ON the master switch and the electric
fuel pump. Move the mixture control lever to full RICH and
engage the starter by rotating the magneto switch clockwise. When
the engine fires, release the magneto switch and move the throttle to
the desired setting. If the engine does not start, open the throttle
1/2 inch and try again.
(c) Starting Engine When Flooded
The throttle lever should be full OPEN. Turn ON the master
switch and turn OFF the electric fuel pump. Move the mixture
