I have 9 spare OMC carbs for 3Holer 49 inchers here to spare outside of what there is for the motor. Being a high speed needle tuning freak who loves to tune with test wheels, tachs and temperature sensors I would sure like to know if one can successfully change a tripple set to high speed hand twistable needles instead of fixed jet inserts to do the tuning? Anyone handy can do that sort of conversion but does the carb really lend itself to it to begin with as some carbs due to their design engineering just don't? Anyone have the experience posting to this question will always be appreciated.
