Default LT4 Cold start

my LT4 (all stock) runs really really rich on a cold start. The exhaust fumes stinks out the enitre house (attached garage). It's dumping so much CO, my CO detectors go crazy.

My TPI motor ran mush cleaner when cold.
Is this just the norm for the LT4, or does it have a cold start pattern?
thx

Mine doesn't stink at all. Also have attached garage, can't smell a thing in the house. Now, start the '74 in the garage and that's a different story...
