No, I think you are on the right track.

Are you running the JD Kit?? That needle makes a big difference.

If not run the R needle P/N 16204 MEN 671 on the 4th clip. Its about $ 14 from the dealer.

The AP mod consists of putting an O-ring on the throw arms of the Accelerator Pump thus reducing lag time between throttle movement and squirt.

PM with your e-mail address and I'll send you the whole mod on PDF. Most of us only do the first part with the o-ring. That is enough to eliminate any bog.
