Carburetor sockets and compensation tube
See Figs. 73-29/1, 73-30, 73-31 and 73-32.
3.4.3.1) Carburetor socket
The carburetor attachment on the engine is designed to
ensure that it can be securely fixed to the intake manifold with
carburetor sockets (1). See 73-00-00 sec. 3.1.
In addition to chemical strain due to fuel and UV radiation, the
carburetor socket is also subject to stress as a result of
vibration. Tightening the attachment clamp (2) too firmly can
also cause damage to the sockets and distance sleeve (3).
Tightening torque 2.5 Nm (22 in.lb).
Compress carburetor socket in the area of the carburetor
connection to allow easier detection of existing cracks (4) and
(5). Also pay particular attention to the area of the inner
diameter (6).

WARNING: If cracks are suspected, fit a new carburetor
socket. See SB-912-030 and SB-914-
019,”Cracks, wear and distortion on the
carburetor flange”, latest issue.
3.4.3.2) Compensation tube
See Fig. 73-29.
To simplify carburetor synchronisation a new compensation
tube (7) has been introduced. See therefore the latest issue of
SI-912-020 and SI-914-022 “running modifications” respec-
tively.
Normally it is not necessary to unmount the compensation
tube, should this however be necessary, then the springs (8)
have to be unhinged and the hose clips (9) have to be
loosened. The hoses (10) have to be cut for removal.
