would a twin Webber have a rerun to the tank , I got the new kit started today just to check it was a good engine . v6 3.1 ho yes
there is a return pipe from the carb with a bolt in leaking like a truper from the top of the carb, I dont see any reason for it other than a return is it ?. dont remember seeing a return pipe on the tank when I took it off it was a while ago
