If it is only having an issue when cold, first pass then is fine the rest of the day why do you think it is a carb issue? Maybe the car needs ot be warmed up more beofre the first run of the day?

Having said that I would do as suggested and play with the idle and intermediate bleeds. It is pretty common knowledge that dominators are pig fat at idle and most are on the intrermediates as well. Being on the stop is not gonna help any. I would look hard at go up on the bleeds a bit on both. If you are going to leave on the stop you need to make it happier down low, IMO. We played with mine a bit to get it happy on the stop. I am on it for a good amount of time and took some tweaking to get it happy there.

Then again if it is only happeneing on the first "cold" pass maybe it just is not getting warmed up enough. Just my Having said all that Warren does pretty good as a racer so it cant be that bad
