My money is on the theory that the mixture screw seat is wallowed or 
likewise boogered and the screw won't seat securely enough to shut off the 
fuel flow.   Tighten the screw and it keeps on running.    That's about all 
I can figger, because the car (before this second issue came up) ran like a 
champ, smooth transition between off-idle and WFO.

Doublechecked and weighed during the last overhaul/reassembly.   By the 
way, the tailpipe on this car is clean.  No over-rich running mixtures.

Fuel pressure regulator is in place and set for 1.75 lbs, plenty for a Y.

And the Carter Y is childs-play compared to the Carter BBS 1xbbl supplied 
to Mopar /sixes made in the smog years.    Damned thing had three jets and 
two different metering rods, all to fight smog.    Nothing like the 
simplicity and reliability of a carb designed without government 
interference.
