Seems like with your talent, you could make up a bracket for the carb. I start with a solid piece of cardboard, like a cereal box and start cutting, bending, and imagineering what I think I want until a shape starts to reveal itself and refine it from there, often, it's nothing like what I first envisioned. Some days, I use up all 4 sides of the box making "prototypes" and it may take a few days of letting the shape materialize in my mind to get where I need to be. Keep an open mind and let the shape become what it needs to be, not necessarily what you "think" it should be...
You can do it.
