Vacuum line help
Ok...
Finally got the Vette up and running today...
We ended up replacing the coil, because the old one was a POS that wouldn't cause a spark at all. Also replaced the points, condenser, and cap/rotor, since the old one was shot.
Car fired over, idled poorly at first, but my dad fooled around a little bit with the dwell and the car seemed to idle a bit more smoothly. (Tomorrow, timing & carb tuning a la Lars's tuning sheets will be done to bring the engine up to better speed.)
Anyway, here's the issue we're having: we're trying to figure out how the vacuum lines are supposed to be run, or where they are supposed to be connected. The '74 manual doesn't cover where to connect them; does anyone have any documentation or layouts of the vacuum lines? I need some way to make sure everything's hooked up right, especially the headlights, since they're in the up position right now.
I DO hear a hissing noise when the headlights are off, and that noise is coming from inside the driver's compartment, but I'm not sure where to track it down...Anyone have any suggestions?
