Vittorazi Motors Moster 185 Plus Maintenance Manual page 64

Check that the return spring is intact and not deformed, particularly in the area shown in the
photo, otherwise replace it.
Insert the spring of the hooks on the central pin and turn it, if any blockage or jamming occurs
the pin and structure must be replaced.
Failure to replace a worn pin can block the movement of the pulley and thus prevent the
manual starter rope from being rewound correctly.
