I put the carb on when I got it in December or there abouts, it was running okay right out of the box, but needed to be tuned. I had to rejet, and adjust fuel level, minor adjustments I think you would do on any carb out of the box - same as I had to do on previous carb. I liked the look, the price and the performance. I have no issues. People either hated the 4010 or loved them, like anything else the people who hate something are going to speak louder. I have a racy cam on my 351, and like the carb before, I had to clean it, rejet it and tune it...
