I acquired a couple of SU H6 carbs (AUC878) but unfortunately they are both back carbs and therefore neither of them has a vacuum advance port. Is it possible to drill a hole and tap the hole in one of the carbs and mount a vacuum port? If possible, does anyone have detailed specs on where the hole should be drilled and detailed instructions on how to go about doing this? Also, where would I get the proper fitting to screw into the carb? Thanks for the help!!
Regards,
Bob
