adjusting SUs questions 120-130 1967

When I try to adjust the idle mixture on my 'new' SU set up it seems like the jet adjustment has a very narrow range where the idle speed is at its peak. Is that normal?

When I get to the peak idle speed plus one flat, and lift the slide with the pin the engine speed drops off 200+ rpm. Getting it so the rpm does not drop so far takes me a long ways from the mixture adjustment in step 1. Any solution ?

When I turn the car off it runs-on like the idle mixture is way off. Is there a newer ( better ) procedure for adjusting the idle mixture ?

Thanks

Greg
