It's been about a year or so since I bought one of Ken's QJets and I just want to give credit where it's due. I've put a couple thousand miles on the car with that carb at least, and I couldn't be happier... Not only happy with the carb itself but with Ken's willingness to answer all of my questions at length over the phone to make sure I was buying exactly what I wanted. He sent me an 800CFM model and the car ran great right up until it blew the head gasket last month!... So maybe the carb works a little TOO well? Thanks for all the help Ken.
