Gomer, you're doing great, except for one thing.
If the idles are perfect, and the mains are perfect, leave them alone. Is it crisp sounding? Leave them alone, if it's too lean at idle or slow speed then yes increase them. Likewise if the mixture is perfect at WOT above 3000 then mains are good.
A larger air jet is the opposite of what you want. To make the transition richer, you need smaller air correctors. The smaller jet(means faster air) and pulls more fuel and makes the transition earlier/richer. Go one or two sizes smaller on airs. If that doesn't work for you, you'll need emulsion tubes that richen the transition. For example, F7 usually comes with 40s and F11 usually comes with 44s.
Keep at it, you're close now.
