Did I distroy my catalytic converter by running too rich?

I Just recieved a new fuel distributor and control pressure regulator for my 77 450Sl. I did the basic adjustment of turning the mixture screw until fuel neither rose or fell in the injector ports. I was able to get the car to start but and it idles ok in P but in D it idles terribly and coughs or dies. DO I need to adjust sytem pressure? I have a CIS pressure guage but don't know the correct system pressure or how to adjust it. Can anyone help please?

Thanks in advance,
