NA mr2 idle speed

i have a 92 NA mr2 my car is idleing around 1100-1200 it should be like 750. the idle screw is turned all the way clockwise already. The dist cap, rotor, wires, and plugs are all new. What do i need to do to bring it down to 750.

also it is idleing smooth its not rough at all, just a little high.

Wait for the car to warm up, and don't have A/C or headlights on, and you'll be ~800rpm

EDIT

Ok, sorry for the sarcastic response earlier...

Make sure you don't have air in your coolant, or the coolant is too low.
