Carburettor Assembly - Vittorazi Motors Moster 185 Plus Maintenance Manual

Check the vacuum hose: there must be no cracks or damaged areas, otherwise replace it.

3.4.3 Carburettor assembly

Replace the diaphragms and gaskets (10, 11, 13, 14, 20, 21). Take care to select from the spare
parts kit the components identical to those to be replaced. For example, the photo shows
two gaskets with a similar but not identical geometry, therefore not interchangeable. The
incorrect choice of these components compromises the correct functioning of the
carburettor.
Assemble the carburettor components without temporarily inserting components 20, 21, 22, 23.
Place the Walbro tool on the metering lever to check the correct height.
