the way to limit a carb is in the jetting. Or some way of holding the butterfly at a certain place, however this type of limiting is illogical unless done to stop the cam destroying valves but we are talking rediculous revs thereabouts.
Judder can be caused by tracking and/or valve bounce either is fairly distinctive. A limiter on an ecu will still be pulling power but just stops going faster. On a carb you will feel the engine run out of steam.
you could say an ECU one is running out of steam at that point as well, as the spark only gets applied to the plugs if the RPM detector says "last turn was at less than (eg) 6500rpm" ... so p'raps half the available power, or less, only gets put down in the lower gears, maybe 2/3rds in 3rd.

true, however mine is still pulling when the limiter holds it back at 6.2k
6200 sounds awful low.. sure it's not just run out of steam? Floor it in neutral and check, would have thought that's the wrong side of the red line to be limiting..
