Can anyone help with my problem?
My V12 will not start unless I remove the plunger at the top of the carbs, all four, and replace them as I do this I can hear the piston in the carb reseat itself back to the lower position, this happens hot or cold, once it has started the car accelerates normally and very smoothly with no hesitation, spluttering or holding back but once you try to return to idle she cuts out and will not start unless I remove the plungers and replace them with the carb pistons reseating themselves.
I am baffled with this problem and would be grateful of any advice
