X3 I know what you mean. If you don’t have the stock set up…manifold and elbow, you tend to lean out a cylinder.
I added a phenolic spacer under my carb. I drilled a hole (1/4”?) and added a nipple directly between the two front primary holes so that the hole opened into both primaries. It’s been working fine for years.
I'm a hobbyist. Not a professional. Don't be hatin'!
