Cutting out at higher RPM's

My brother has a 87 Sarah, he has put a weber carb on it and did a "nutter bypass “ I believe that’s what he called it, anyway I adjusted the carb and set the timing today and the thing runs great until it reaches 3000 ish rpm’s then it acts like it has a soft touch rev limiter on it, throttle response and idle are perfect its just the upper rpm range he has changed the cap, dist., rotor, and the coil also. He said that the tach quit working one day for a little while and this started and coutinued even after the tach started working again. It has a stock 6 cyl, any help would be greatly appreciated.

When I remove the tach wire from the coil the thing wont start. Doesn’t really act like its a fuel problem more like its running out of ignition “fire” . The advance is vacuum checked it and it seems to be working also.

Did you get this figured out? I have the same problem. I have just replaced the airfilter with a dry filter that may be more restrictive, so I have disconnect the battery for 20 minutes so the computer codes will reset. I'm hoping this helps. Let me know what your fix was. Thanks
