Old man with old car, new here with questions

Nice work, onward and upward. Still some choke work to do, looks like. Where does your hose run that you've got connected to the large nipple just ahead of the driver-side carb hold down nut?
Hi Dan, the hose vacuum line at the carb base is connected to the inside of the dash, I have not checked where it goes but I believe it is for the heater system. The vacuum line on the other side of the carb goes to the distributor vacuum advance. The power brake booster comes directly off the intake manifold and then tees into a vacuum tank located in the front drivers wheel well.
I will have to trace the line and also do a vacuum leak test.

I have ordered a voltage reducer for the divorced choke that can take me from 0 to 11 volts. It is an experiment for me. The cost was $6. I believe I can control the speed at which the choke opens.

The question I have to finish the fuel system off is to find a grommet for the fuel fill line to the tank. Presently they used a hose that reduces down but it leaks. They also cut off a small piece of the metal fill line. This is what happens when we want challenges in life. Since I still have it sitting on cribs I need to finish the trans first. Hank
