The CarterBrocks are not a bad design carb, there are just better choices today for most of us. I rarely install them mainly due to 3 issues; they often have a poor tune out of the box. They are more difficult to tune and to find tuning parts for. And there are superior designs readily available.

Compare the price, tune and design features of the new Street Demons, and I do not understand why anyone would buy a CarterBrock.
