Lever System on

Carburetor

Removing bell crank "G" and lever "H"
Removal:
- Remove the carburetor –
see 11.6.8.
- Carefully pry bell crank "G" and
lever "H" off the shafts.
- Remove the lever system from
the shafts.
- Take the torsion spring off the
throttle shaft.
Installation:
Note: Bell crank "G" and lever "H"
have to be pressed onto the shafts.
To do this, clamp the carburetor body
in position so that the pressure used
to install the levers is transmitted to
the carburetor body via a short part
of the shaft and the retaining ring. This
procedure ensures that the shaft is not
loaded beyond its buckling strength.
