Where does the vacuum line connect to the intake system for a retard type distributor?
I have a port on the intake manifold that also has the brake assist port on it.
I have another port on the aft carb on the topside of the carb body right by the flange area, just before the isolator pad.
I also have a port on the forward carb, on the bottom of the carb body right by the flange area.
All unused ports are plugged or capped off.
I looked at various cars at the show and there did not seem to be a consistent attachment point.
The port that comes off the intake manifold seems to have vacuum all the time, and it seemed like I remembering trying it and I did not see the distributor advance when connected there and the engine was revved.
The one on the aft carb only pulls a vacuum when the engine is revved up, and so does not retart the distributor to 4 ATDC at idle. Is this indicating some other problem?
The forward carb port does have vacuum at idle, does pull the distributor to 4 ATDC and allows the distributor to advance when revved. Seems like the right one. However it was blocked off when I bought the car. When I took off the cap to try it, fuel dripped out. Just a few drops.
Is this indicating a incorrect fuel bowl level?
I used some clear tubing and can see that this happens.
I have been running the car with it connected here, but I can't seem to get a consistent smooth take off from a stop sign. The engine wants to hesitate or stumble. It seems to do this with the carbs set lean or rich, according to the plugs.
Seems like I might be chasing my tail so I wanted to confirm where to connect the distributor vacuum at?
Thanks
