Recently, success with the CarterBrocks has been hit and miss. When they work right, they are very dependable. But when they don't, they can be a pain to get right. And tuning parts are more difficult to come by for a lot of guys.

The two things that I have had to do to most of the CarterBrocks that I have messed with are; changing to stiffer step-up springs and adding weight to the counterweights on the secondary air valve.

If you can find a clean used one for a good price, it might be worth it to try one. But if I were going to spend the coin for a new street carb, it would be the new Street Demon.
