OK, can’t quite make sense of the exhaust housing picture your posted, how did you repair that hole in the exhaust housing near the mounts? In any event, I have several exhaust housings from skeletons if you need one.
Again, the symptom you describe is not uncommon for some of these engines. Bringing the RPM down slowly and holding it at the one flat spot will often cause the engine to bog and just stall out. Usually leaving the mixture a tad rich solves the problem, but you claim the needle is out 2.5 turns. Are you sure the throttle plate is closing fully, just cuz the cam isn’t touching the roller doesn’t mean the butterfly is closing fully. The linkage could be jammed/rusted, butterfly and shaft might be binding also. The only way to tell is to remove the carb and watch the butterfly from the back of the carb. I usually have to leave the cam pick up a bit retarded on some of these engines as well to avoid the symptom you describe.
