LUBRICATION AND MAINTENANCE WORK – CARBURETOR
Check the carburetor synchronization with an vacuum
gauge and adjust if necessary
– Disconnect the vacuum hoses from the air filter box
1
and from the
secondary air system valve
2
and run up on the side between the
frame and the air filter box.
– Mount both tanks and connect the fuel lines, open the fuel taps.
NOTE: before you use the special tool 600.29.011.000, always check
both dial gauges for synchronism:
– Connect both dial gauges to one cylinder with the vacuum hoses and
a T-fitting.
– Tighten the knurled nuts on the special tool by turning them in a
clockwise direction almost to the stop.
– Start the engine and unscrew the two knurled nuts until the dials
barely begin to vibrate. You should still be able to read the gauge
clearly. Both dial gauges should indicate the same value. If not, the
special tool is damaged and should not be used.
– Turn off the engine, disconnect the hoses and the T-fitting.

(choke) is completely closed and the engine has reached operating
temperature.
