15.4) Requirements on the throttle lever
See Fig. 59.
From throttle position 108 to 110 % the boost pressure rises rapidly and the throttle
becomes very sensitive in this range. Therefore try to prevent operation in this small
range or if setting for take-off performance pass this range quickly.
Consult also the section "electric system" for the description of the system.
For this reason it is recommended to assist the pilot with an visual/manual arrange-
ment at setting for max. cruise performance.
A detent on your throttle lever at max. continuous power would be most suitable.
Provide this detent at throttle position 104% corresponding to 8 - 9 mm (5/16" - 11/
32") travel before full throttle stop.
The sketch (Fig. 59) depicts a feasible arrangement.
The throttle lever is pressed onto throttle gate and comes to a stop at max. continuous
power. Against the spring force the throttle lever will be released from the detent and
can be moved further to take-off performance.

■ CAUTION: Adjustable positive stops for idle- and full throttle position are of
course required.
These stops have to be designed such to render adjustibility and to
prevent overload of the idle stop on the carburetor.
