3.4.2 Carburettor maintenance

Immerse the carburettor case in a container containing solvent for a few minutes. Carefully clean
the carburettor body and covers with a brush, removing any gasket residue. Then gently blow the
various parts with compressed air.
Pay particular attention to cleaning the mesh (highlighted in the photo) and the metering lever
needle.
Check the condition of the diaphragms: they must be soft and free of cuts, otherwise they must
be replaced. For routine maintenance, follow the table.
Check the needle: the tip must have a conical shape as shown in the figure, otherwise replace it.
