The felt filter (N/1) of the fuel filter can become clogged. It is
recommended to replace the fuel filter once every three months
in order to ensure unimpeded fuel flow to the carburetor.
To remove the fuel filter for replacement, pull it out through the
tank filler neck using a piece of wire bent at one end to form a
hook.
