a photo of what your looking at might help.
If its the idle air screw in the back of the throttle body, make sure the O ring on it isn't flattened out.
Otherwise you can suck in too much air and not set the RPM correctly.

A ha thought it was the idle screw.
But that's worth looking at also.
These often shrink or get a flat spot so send the car running funny.

You really need to get it hooked up to a Exhaust gas analyser to read the CO, a garage which does MOT will have the equipment to check it.
Before setting the Mixture you need to make sure the car is fully serviced with a clean air filter and timing spot on then get the mixture adjusted as that's the last thing to mess with.
1.5 to 2 % is what you are looking for.
