After I validated the TDC mark and the case half/split are aligned, I started the engine --- first time in 2 weeks.
Again, the cold idle started ~ 500 or 600 RPM, and seem to struggle. So, once again, I turned the idle screw CC to get it up to ~ 900. Then, once the temp engine started to warm up, it settled ~ 950.
That is when the engine starts to do a small hunting/surging cycle. Each cycle is ~ 10 seconds and the idle moves just a few hundred RPMs, and comes back down. Up/down between the 1K mark and the one just under it on the tach.
It is certainly not the up/down by 500+ rpm every second or two type of surging/hunting like what you see here:

I will to a cold start again tomorrow to check if the idle again starts at 500 ~ 600.

@Bruce - thanks for the comments and posting your fotos. They do help me visualize how the housing is mounted.
I will go back and look in the engine bay - check alt housing TDC mark & how it aligns w case center line.
I must say beforehand, it is so crowded back three, and dark. Really hard to find stuff let alone take a clear foto. But, I'll look for them and try.
