in place to fit the carb
i tried a diy manometer vacuum pipes on the carbs in to 2 mc donalds oj bottles with a pipe to balance them 1/2 filled with water and they concertinaed to
about 2" tall in seconds did make me laugh i spent about an hour making them and going throw the cupboard getting permission to have a tupperware box drilling
it for the pipes finding one just rite size so the bottles sat level thinking this will be a useful tool i will have for ever
