Who is running a Quikfuel 450 on their Slant

Check for vacuum leaks. Is the choke hooked up, if electric it will need power or you will have issues. I'm not familiar with the /6 but how is the carb mounted as in is it sitting on an adapter? You have a 4bbl manifold? I know the /6 Distributor gear is plastic, any change this is dancing on you making the idle erratic?
