Anti-Stall Dapshot, Parking Brake Assembly, and Mystery Vacuum Line

[64thunderbird]

Hello

The 1964 shop manual has an illustration, with a vague description, of an anti-stall dashpot . This is missing from my car, and although ye olde Holley carb is not tuned properly yet, my car wants to stall when I stop and go. Everything is grand if I'm doing above 40 mph. I wonder how necessary the anti-stall dapshot is, and if that is a part of a problem. The shop manual suggests that after adjustment - put the car in N, turn it off, then connect the vacuum power line to the vacuum power unit of the automatic parking brake assembly. My car does not automatically release the parking brake when I shift, as it should, so I suspect a vacuum mis-fire somewhere.

My questions are:

I. Is the anti-stall dashpot necessary, and is the fact that it's missing an indicator as to why I have to two foot it around town?

II. Where is the vacuum power unit of the automatic parking brake assembly?

III. Does anyone know what the cut, dangling line from the passenger side firewall belongs to? It is not grouped with the other vacuum lines - from an opening closer to the right hood hinge.

I'd appreciate any insight into these questions. Thanks

Sounds like you have a vacuum leak. The hose on the passenger side is for the parking brake release. It should go up to the intake and connect near the carb. That could be your vacuum leak and the reason the car does not idle.

I'm thinking you need to supply more information. Why a Holley carburetor? I'm guessing your car does need the dashpot to prevent the need to "two foot". The parking brake release vacuum motor is located on the parking brake assembly above the LH kick panel.
"cut, dangling line"? Would that be a vacuum hose? If so, what size? Two hoses come through the firewall in the area you refer to: vacuum for AC & vacuum for power door locks. Do you have either or both?

Such mystery - door locks, parking brake, and - or ventilation. I'll figure it out, and when I do, I'll post a diagram. I just really don't want to destroy a car that I love, or take her to a shop where the workers have the same questions that I have.

I don't know why my car has a Holley carburetor - I found her covered with leaves in an alley a few months ago, and bought her devoid of keys. For some reason, I am very impressed with how well she has survived, and the fact that even a woman, like me, can keep her going - since I was not raised to tinker with anything fun.

Thank you for the responses; I now have part of a piece of the puzzle.
