150 Giubileo carb problem

Post by rickshaw » Tue Jun 19, 2018 12:44 pm

Hi I have had problems with my 1964 Gilera it will not run on idle, I have noticed that the idle jet is very high up in the carburettor so have moved the float higher up on needle which seems wrong as there is only one setting, the bike now seems to run ok but it must be near to flooding could some one help please the carb is a UB20BS.
Thanks Dave.
