				 Idle rpm changed with air/oil sep installation... 
 ...in the PCV system.  I have a QuickFuel SS750 carb that was tuned quite well until I needed to install an air/oil  separator in the PCV system.  The idle dropped from 850-900 rpm to about 700 and less, apparently due to the new restriction in the PCV line to the manifold.  Sometimes it would just die.  I used the curb idle screw to regain my target idle rpm, but then the engine would overrun/diesel when I shut it down. 
 
I don't like dieselling, but having to heel and toe at every stop just to keep the engine running isn't a lot of fun.
 
Suggestions on how to recover idle rpm without the evil dieselling?
 
Thanks in advance
