Items noted 1:Using Dave Darling's diagram the line coming off the throttle body to the cap side port of the vacuum advance unit is plugged with a screw and not connected to the vacuum advance unit shown in top of picture. Does this line need to be connected to the cap side port of the vacuum advance unit? 2: The line from the back of the vacuum advance line is omited because the car is a 74 and does not have a port on the throttle body. |

I have not got a chance to work on the car in a couple of days, work and snow getting in the way. I do have a couple of questions.
1: The line from the TB that goes to the vacuum retard was not connected and plugged with a screw. The car at one timewas running great with this line like this. Why? 2: Before I take the entire plenum off, what would happen if I removed the air cleaner, started the car, and put my hand over the TB? Could I eliminate the cause of the vacuum leak by doing this, and can I do this? Kevin, I got your message I just got home really late last night and tonight. I will give you a call tomorrow about all this. Jack |

1: The line from the TB that goes to the vacuum retard was not connected and plugged with a screw. The car at one timewas running great with this line like this. Why? Unknown. It isn't really needed that much for the car to run, but it would bring the idle down slightly to have the vacuum retard hooked up. (You're talking about the line to the fitting on the distributor dashpot that points back toward the distributor body, right? That's the retard. The advance points away from the distributor body.) QUOTE 2: Before I take the entire plenum off, what would happen if I removed the air cleaner, started the car, and put my hand over the TB? The engine should die; if it does not you absolutely have a vacuum leak. --DD |
