14.7 is the one number the OP can target and be fine, not necessarily perfect, but fine. We can get into a lot more intricacies of this, but it would simply be over the OPs head. I readily admit that the 14.7 target is not likely optimum, but the OP doesn't really have the abilities to set the cruise any finer. The idle and WOT, he can.

Rather than limiting yourself to criticism, why don't you suggest the best process for a carb noob to set his cruise ratio. He has no tools, parts, or recording ability. At this point, anything more than I suggested will bury him.

I was only trying to help a noob get to an acceptable point, not give him an engineering lecture.
