Not sure I fully understand your question. I used a .037 Quickfuel bleed with a shoulder from a kit, then changed back to the original .031.
It's just weird to me that I can adjust the mixture screws to get low 13's at idle in gear ( the mixture screws are only about 3/4 turns out) , then by 10 mph it's going rich and by 20mph it's at 10.0 and stays there up to at least 50mph. I didn't drive it very far or get on it to see what it does beyond that.
I ran late doing yardwork, and couldn't get back to it. I will pull it back apart and blow out all passages after work. Maybe some speck of something is in the passage, partially blocking the air when it starts sucking?
