Connect the carburettor's fuel inlet pipe (highlighted in the figure) to a pressure switch via a tube.
Set a pressure value lower than the values in the table and check that the needle of the metering
lever does not allow air to escape. Carry out further tests by gradually increasing the pressure.
WB3A
1,05-1,15 bar
Air must only escape from the metering lever needle within the pressure range indicated in the
table.
In the event of a fault, measure the height of the metering lever again and replace the spring (17)
if necessary.
Once the above checks have been carried out, fit components 20, 21, 22 and 23 to the carburettor.
