vacuum brake
The vacuum brake is attached to the side of the carb on a bracket. It has a vacuum actuated plunger that is connected to the choke butterfly shaft. The vac brake has a vacuum hose attached to the base of the carb. It's hard to explain it when I don't totally understand it. It sounds like 4 barrel carbs don't have one of these things. I know most guys have 4 barrel carbs but this car is totally original except for Thrush mufflers and I'de like to keep it that way. At least for a while. Thanks again.
