KV engine rev limiter

MSL · 26-11-12, 01:41 PM

1986 Coupe Quattro 2.2.
I have removed to standard rotor arm for a non cut out one.
The engine revs cleanly to about 5200rpm and then starts to sound harsh and strained, if that makes sense.
At about 6000 rpm what appears to be some other form of limiter cuts in.
Does this engine have a fuel cut off limiter as well?

Thanks
