Re: Resurrecting my 56’ Patrician

Just an update:
I have disassembled, ultrasonic cleaned, and reassembled my backup carburetor after I had a short back and forth with Chicago Carburetor about the gaps in the base plate to bowl gasket. They assured me these were required. While trying to locate any vacuum leaks, I did discover one of my exhaust manifold gaskets was askew. The bolt missed the hole, and I missed the mistake. That has been fixed. New gaskets and new bolts. Did find a leak though. The metal tube going into the vacuum reservoir for the power brakes, easily slides up and down in the top of the tank in the driver’s fender. It is on the list of issues to address. I installed the 2nd carb yesterday and with the whole 40 minutes of daylight left after work, I started the car and allowed it to warm up. Connecting the vacuum gauge to a port before the one-way port for the brakes and blocking off the line for the brakes, I witness 20” of vacuum on choke, then after the choke was fully opened, it stayed close to 15-16”, only going to 20 with a slight rev of the throttle. Again, I adjusted the fuel mixtures screws ¼ of a turn at time, in and out with no real change in vacuum. I know its operator error; I just do not know what I am doing wrong. The only source of vacuum that is not blocked off or gauged is the vacuum advance to the distributor. I will continue to watch the you-tube videos, but they seem more for the 70’s 4 barrels. I also purchase a car cover. It came vacuum packed, and when I released the vacuum, it opened, its huge. Did not mentally connect how big the Packard is till I tried to carry a bag for it.
