If you really want to frame that carburetor like a relic, make the broken parts a pattern—think negative space, a subtle gradient of rust. Keep the edges clean, maybe paint a single, bold line across it so the eye stops on the geometry, not the grime. A little chrome polish on the valves could give a sharp, almost mirror‑like finish, but remember, the whole thing has to look intentional, not just a dented piece of junk. If you can get it to function, that’s a nice bonus, but first focus on the visual rhythm, then make it work.

Sounds solid—just keep the rust flat, line sharp, chrome minimal. Let the shape echo the original, so the rebel vibe stays clear and not cluttered.
