Of course your correct to say that there should be a coil in the copper pipeing, but as fido mentions there is no room and indeed there isn't as I'd liked to have inserted one. Between the carbs there is a rubber/cotton type pipe to deal with vibration. Probably just as well because I'd never have got me fingers in there to polish the copper!

Fido... I'm still working on the spindle size problem, will report when done.
