The situation you had earlier appeared to be rich at idle or was it just off idle as you started to open it up? I don't have a full picture of what the symptoms were at different revs/throttle settings with those different pilot jets and air screw settings.
In other words, if you can get the idle OK with say a 30 pilot jet but it bogs as the slides are lifted to say 1/4 open then it is likely to be an issue of transition from the pilot circuit to the main circuit and that's where the cutaway comes in to play. If it's wet and soggy at say 1/4 to 1/2 it's more likely to be the needle jet.
Easy check on the air circuit would be to remove the pilot jet , loosen the screw and spray carb cleaner down teh air inlet. If it sprays back in your eyes, you know it's blocked (and you need to see an eye specialist) If it sprays out of teh pilot jet holes (up or down) it's probably not a problem.
