hey lads

i never do make sense
hahaha
but neways
what i thot was th idle screw actually is the fuel mix screw
i turned it down and it did adjust the rpm of the car
it must have been runnin a fair bit rich...
so im gona turn it back up a tad and then turn down the idle screw

should i do all this with the car running??/
or make the adjustments then get the car going???
thanks again

Yes do all adjustments with the car running then you can hear when running rich or to lean and see what rpm you are at. Don't forget to the rev the car to around 2k for about 5 secs after each adjustment.

Like James said, blip the throttle after every adjustment, then let it settle, turn the idle speed screw down to the lowest rpm that it will idle at and adjust the mixture screw to get even running. Take it to your local mot station to get it fine tuned at idle for best running/ emissions.
