Refitting the carburettor
- Before refitting, wash the carburettor body accu-
rately with a degreasing solvent and compressed
air.
- Pay special attention to the fuel supply pipe and
the plunger seat.
- For the minimum circuit, make sure the following
points are properly cleaned: air gauging, outlet
section controlled by the flow screw, progression
holes near the throttle valve.
- For the starter circuit, blow the connection pipe
properly with the jet. This is necessary because
the nozzle support hides other inaccessible inter-
nal calibrations.
- Blow the intake nozzle properly.
The acceleration nozzle outlet is extremely small
and is oriented to the throttle valve.
- Check that the carburettor body has the closing ball for the idle circuit pipe.
- Check that the coupling surfaces, the tank and the diaphragm are not dented.
-Check that the depression valve housing pipe is not scratched.
- Check that the throttle valve and the shaft do not show abnormal wear.
- Check that the plunger seat does not show abnormal wear.
- Replace the carburettor in case of irregularities.
N.B.
TO AVOID DAMAGES, DO NOT INTRODUCE METAL OBJECTS IN THE ADJUSTED SECTIONS.
