They are, even better is a rebuild done by a pro. Most of send our carbs to Ken at Everyday Performance or Mark at Q Power. Either way you can’t go wrong.

Thank you guys! I looked at the kit and will buy it. I decided to take the plunge and rebuild my QJet myself. It has been really rewarding to learn about it. I might completely screw it up, but I figured when the hell would I ever get the chance to try it?
