I want to understand the relationship between fuel level and emulsion jets. Anybody? I've searched and searched but no luck....
My carb is a 3310-1. Reason i'm working on this circuit is because when running WOT i see the AFR grow lean from 12.5 to 13.8. RPM dependent. note: i need to go put a fuel pressure gauge on the hood and run it to see if it's fuel delivery problem not a carb situation.
