That's tthe weird thing about it...

arround teh 3 - 4 K there is a hick up in the revving... but after that it runs fine again.

CO value is set on 1.5%
ignition was set on 12 degree

So this makes me think it's got something to do with the meteringhed unit (wrong setup ?) or the airhose which I've changed... ?

Thanks.
