Mode of action and setting the throttle/brake linkage
With the throttle/brake linkage, two functions are carried out at the same time via two servo steering
levers that are at 90° to each other.
Sliding the "carburetor slide" via the throttle linkage, regulates the air supply to the engine.
At the same time, the idle nozzle needle (conical needle of a needle valve) is moved, thus changing
the amount of fuel that flows through the carburetor.
If the throttle linkage is moved further than the idle position (mechanical limit stop of the carburetor
slide), the servo lever pushes against a spring buffer.
Now the sphere of action of the brake linkage comes to effect, it presses the brake shoes of the disk
brake together via an eccentric tappet.
The position of the adjustment rings (the mechanical limit stops) of the stop spring on the
throttle linkage and on the brake linkage must be adjusted to the mechanical limit stops of the
carburetor and the disk brakes.
Mounting the carburettor control
A visual check of the carburettor passage is possible after removing or before attaching the air filter.
•
If necessary, correct the idle position (maximum 1 mm open carburettor passage) on the idle adjust
screw (throttle stop screw).
The idle speed adjusting screw is the little screw under the air filter.
•
Mount the throttle control linkage by screwing a ball socket onto the short thread rod.
•
Attach the ball socket to the carburettor slider and
•
slide a spring onto the linkage.
•
Screw an adjuster ring (accessory bag) onto an arm of the four-armed servo control lever.
•
Guide the linkage through the adjuster ring on the servo control lever.
•
Loosely slide an adjuster ring onto the steering linkage and secure it.
Assembly of the brake control
•
Insert the brake control linkage from below into the servo arm left of the carburettor control and
slide on an adjuster ring.
•
Guide the brake control linkage through the brake lever .
•
If necessary, shorten the linkage.
•
Position the servo control lever onto the servo shaft in such a way that the throttle and brake levers
are in neutral position.
The throttle/brake linkage should have the following impact:
•
A) Full throttle: Carburetor slide fully opened, brake has no impact
•
B) Idle speed: Carburetor slide fully in, adjusting rings are loose on the brake levers.
•
C) Brake: Carburetor slide fully in, throttle linkage presses against spring resistance, brake lever fully deflected
