Thanks ECRider.
I went back to my original setting of CCK #3 42PJ, 180MJ and #8 slide. This worked really well in an extreme rocky enduro with lots of uphill rock crossings. It was just a wee bit lean when doing transfer sections (made knocking sounds when closing the throttle after keeping the throttle pined for over one minute) and engine boiled over for the first time! O.K. it was 36 Celcius! and only 1st and 2nd gear for over 30 minutes.
So I guess I will raise the needle by half a clip. I also tried CCK #2 with a #7 slide but was a bit too rich of the bottom for my style of riding even if the air screw was 2 1/2 out.
BTW I will never go lower than a 178 main on the 250's.
