I have ran many CarterBrocks over the years. And in years past were often my 'go-to' carb. The basic design is sound and some models do work okay.

BUT, they have waited way too long to make any real updates to the line while some models in the line have had know issues for years. Virtually all of their competitors have been adding models and variations to their lines while the CarterBrocks languish. Then there's the difficulty finding tuning parts and the complexity of the tuning chart, etc, etc.

So while the CarterBrocks aren't necessarily bad carbs, there are simply better carbs out there. We'll see how these new ones work out, but I would be surprised if they out perform or even perform as well as some of their competitors.
