Carry out the above procedure on both carburetors.
◆ NOTE:
The mechanical carburetor synchronization is suffi-
ciently exact.
You must at this point place the throttle lever in the cockpit to the idle
stop position. It is an advantage at this point to enlist the help of an
assistant to ensure that the throttle lever remains in this position during
the next steps of the synchronization process.
As soon as the throttle lever in the cockpit remains is in the idle stop
position, move the throttle lever (1) to the carburetor idle stop position and,
using the cable fixation (4), secure the bowden cable accordingly. As soon
as the two carburetor bowden cables are installed (throttle lever in cockpit
in idle position), you must check that the idle speed adjustment screw (2)
rests fully on the idle stop (3) without pressure.
■ CAUTION:
An idle speed which is too low will result in gearbox
damage, and if the idle speed is too high, the engine is
harder to start.
Start the engine and verify the idle speed. If the idle speed is too high
or too low, adjust accordingly with idle speed adjustment screw (2).
Check the true running of the engine. If necessary, adjust with the idle
mixture screw (6). See 12-00-00, sec. 4.2.
