Is 1250RPMS too high of idle?

I have a 1990 XJ 4.0 AW4 and it idles pretty low. Yesterday I took of the throttle body, and cleaned it out really good.

This made practially no difference in my idle speed, but did seem to give me a slightly better throttle response.

Anyway, I moved the adjuster screw out a ways, and now I am idling at 1250rpms in Park/Neutral, and 1000 RPMS with the XJ in gear.

Is this too high of an idle, or just about perfect?

you want to back it down to 1000 in park/ neutral, so when in gear it idles at about 750

Damnit, that's exactly where it was before I adjusted the screw, but had the spacer in.

Guess I'll take it out and see what happens tomorrow.

Thanks
