Carb tuning, larger accelerator pump nozzle?

@Mattax @yellow rose

Well got the IFR moved down. Plugged the top two Emulsion ports (not sure it "port" is he correct term) so the bottom 4 are still open on both blocks. Dropped the primary jet size down to a 68 (stock is 70) as when I was driving it before it would cruse at around 12:1 and added a 35 pump shot leaving the blue cam. Idle AFR was more stable, got the idle curb dialed in and took it for a drive after fully warmed up and still have a lean stumble coming off the clutch. Transition slot is not over exposed, its close to .035-.040" exposed at idle. Thoughts?
