Worth a try, but it may be more trouble than its worth as the 3/32" 'step' between the bore of the carb and the inlet on the head may upset the mixture. This happened to me donkeys years ago when I pulled a stud out of my Triumph 5TA manifold (7/8"bore) and my local breaker had an 1.1/16" manifold in stock. OK, the 'step' was the other way round but I just couldn't get it to run.
If you want to try a new concentric, then a 622 is what you need.
