Good solid progress.
Trying to save you time here. Don't be fooled with the AC or atomiser. The AC120 and BE5 will get you to the Rally. Just focus on the main jet and pilot.
As you can feel 130MJ is way too big and 38/120 pilot is way too small. The difference with jetting an SI carb is that there is so much more bleed over than other carbs. Every jet affects every jet. Its almost like the whole thing jets in at once.
If you weakened your main jet now with that small pilot you might have a situation. Get a bigger pilot. 45/140 would be where I would start. The first number of your final pilot jet will be 45, 48 or 50. So forget all the others.
Until the main jet is weaker the 1/4 point will feel heavy. Holding steady cruise at a fixed throttle position will show up the situation the best. Aim for 280F at 1/4 and 320F at sustained WOT (but not until you have a few hundred miles done).
