Motor Manual gives choke adjust within 1/32 compared with the factory service manual at 1/8 in ; The float is correct

ok, I am not there to verify and those are the only reasons for fuel dripping into the venturi I have been building carbs for over 30 years.

I will opt out since I can help no further and maybe someone else can help you
