If not you could remove the choke linkage rod to check if it would baseline hot. 6-7 turns out is not the baseline.

my determination of the lean afr is with my afr meter.
my idle bleeds havent been touched. i drilled out my new idle tubes to .042 like how my old ones were.


and as an update to my original post.

i took the carb off to put the 1406 back on so its not a dead vehicle, and noticed the throttle body plate was dangerously loose, and i assume with new gaskets i didnt tighten them enough to make up for the give of the gaskets.

ill put it back on tomorrow morning and see if that was my problem. i swear i heard the noise as if a vacuum hose were disconnected. i assumed it was the air flowing through the primaries.
