necting rod (C) and the throttle cable (D).
Connect pressure tester 531 03 06-23 to
the fuel intake on the carburettor.
Pump up the pressure to 50 kPa.
Lower the carburettor in a vessel with
petrol in order to discover any leaks more
easily.
No leakage is permitted.
Place the gasket on the carburettor hous-
ing and then the control diaphragm.
Check that the air hole in the cover is
open and screw the cover on.
Assemble the jets (H) and (L).
Place the sleeve (A) and the spring (B) on
the jets and slide the components into the
carburettor housing. Note that the cut-out
in the sleeve should be turned to face the
bar in the carburettor housing. Use tool
530 03 55-06 to press in the sleeve and
screw in the jet.
When the sleeve has been pressed in
using the tool, the jet can be adjusted
freely.
Carefully screw the jet until it bottoms and
then screw it outwards.
This applies to both jets.
The default setting is:
H =1.1 turns open
L = 0.9 turns open
