Hi All,
Currently rebuilding the carby and the settings in the Gregory's manual for the primary slow jet are 0.54mm, what is this in reference to. Is it screwing the jet all the way down to the bottom of the port and then unscrewing it 0.54mm or am I completely wrong and it means something totally different. All the jets have different settings in mm but no explanation of what that measurement is in reference to, any help would be greatly appreciated.
