big turbo coosy
 

as above but its ideling way to high can i ajust this with the large screw on the bottem of the pot?and is it in or out and is there anyway to sort thius out other then the screw???????????????????

fist ' l;et it get upto normal operating temp.

then disconnect the idle valve wiring - then ajust the screw under the inlet , clockwise = slower, to about 900 rpm as shown on the rev counter inside, then reconnect the idle valve wiring. it may jump up a couple of 100 rpm and then settle again, but if it goes up to about 1500 rpm and stays there, it sounds like another problem. possible faulty coolant temp sensro (blue on at back of head) or a sticky idle valve.

thanks matty will try today in my lunch brake?
