Dumb Timing Questions

[whitey]

OK...OK, this maybe a REALLLLY dumb question, but!

got the car warmed up, disconnected the vacuum advance and set the timing to 15*; hooked up the vacuum advance again and it jumped to 35*. Is this normal?

You have the vacuum line hooked up to manifold vacuum. There should be two ports for vacuum on your carburetor, switch your line to the one you are not using.

Not only do you have a cool Cuda John, but you are smart too!(I at least hope you are, cuz that was my guess also)

Bill, that Dart of yours is one nice ride too, and great minds think alike.:-D

Just to clarify...

I disconnected the line for the vaccum advance, capped it; left the pcv connected. noticed the change in idle. set timing to 15*, reconnected the vacuum advance and the idle recovered and actually ran better.

Before I set the idle with the vacuum advance hooked up and set it for 15*, when I disconned the vacuum advance the timing ended up at 8*.

You should be able to feel vacuum (or the lack of) at the port on the carb when you remove your vacuum line. You should not have vacuum at idle on the port you connect your line to. Only as engine speed increases should you feel vacuum at the port.
