I agree with H.  The plugs look good.  I don't see any lean coloring.

Rough idle at a cold start with a carb'd engine is not uncommon.

A cold start rough idle, that goes away immediately at warm up, is almost always caused by the air fuel mixture.

Ambient air temperature and air density - Relative Humidity and Elevation (barometric pressure) can also significantly affect AFR.

Why does the carb NOT have a choke or an AAP?  ???

Gnarls.  :gap:
The carb does have a choke and AAP. Both work too. The BVSV that controls both, has a broken nipple on top. I glued a metal tube in so I can connect a hose to hopefully make it work.
45 this morning, started up no issues.
