I just adjusted my mixture and idle screw as I had been advised, Screw idle screw out 5 screws from all the way in, then set idle with accelerator stop screw, then dial mixture screw back until revs drop by 50-100rpm.
So now it is idleing nicely, but it is spitting black shit out the exhaust badly, when I put my hand infront of it I get brownish dots all over my hand, and when bigger drops come out, they look like water with brown oil floating on top??
Can someone please tell me what is causing this/how to fix it?
The exhaust is a newish 2.5" sports exhaust.
