That's great it's running better! I went back over this thread and noticed the carb has a richer 110 main jet (stock is 100). You can try moving the needle clip to the top #1 position which should help a bit more, but I think what's really needed now is a 45 pilot jet, 95 main jet, and ideally a 130 power jet too, which affects mixture from 1/2 throttle up. I would also keep going with the WOT bursts until the engine pulls fairly normally; the new jets will make this happen sooner. I guess it's idling normally now?
Main jets are here (if it were me, I'd get 90, 95, and 100):

I think it's pretty cool you're making the effort to tune this thing. Back in the day, I don't think many people did.
