Hi i was puzzled with the same problem when breaking in a new enigne, clutch would not engage even revved at a pretty high RPM, i have tried pretty much everyhting but problem persisted , i brought my car to a track and have a local expert looked at it. the clutch was properly set and all number looked decent. When i started leaning out, the problem magically improved to a point it was gone. Xray clutch is rather sensitive, so once you start to leaning out your engine then it will work out fine. You numbers look fine, just give it a try hope it helps
same problem here . so i just started leaning out little at a time and it got better
