I am trying to locate were the choke tubes coming out of the intake pipe to. I do have the first tube closest to the front hooked up, it screwed into the choke housing, but the second tube comes up and hooks to a vacum line to somewere. Thats the one I'm trying to locate the piping point to.
Thanks,
Doc

 

Starting at the choke spring housing the tube goes into the tube at the exhaust crossover in the intake manifold the other side comes out of the tube in the exhaust crossover up to the top of the carburator air horn.

Airflow goes from the carb airhorn (top of the carb) thru the heat stove (u shaped tube in the exhaust crossover in the intake manifold) to the choke spring housing ( heating the spring to open the choke) thru a hole in the choke housing and into the carb.
