I have played about with the wur quite a bit internally i would go for maybe say 0.5 mm on first attempt,making sure you knock down evenly also with measuring the height it sticks up at first,, say at postions 12,oclock,3 oclock,6,9 etc.

From memory it only sticks out 1.5-2mm approx in height and before you start knocking it down its best to measure to confirm you have knocked down even all the way round the circumference.

Brass round stop is arrowed in right half shown
The diaphram steel insert in on the left hand picture,,this is what moves with manifold pressure and contacts the stop..

In my opinion you will need rpm switch to stop rich midrange if you adjust this.

P.M me if you need one,i have one for sale(msd)
