The mixture arm on my carb is the wrong type I need for using the Van's supplied cable. Can someone here with knowledge of these carbs help shed some light where I can get the correct type? Can it simply be replaced with no other mods? :confused:I did cross reference the full part number and it is correct for my o 360 a4m. Too bad the engines don't use Holly's, I'd be more at home. Pm's and or emails welcome! [email protected]
