At least you know for sure what your timing is so you can check that off the list. Does that explain your "blasted pinging"?

That still doesn't resolve your plug color issue but it's a step forward.

Hmmm.... confused (again)

I haven't gotten to the step of actually SETTING the timing yet.

That's ok. At least when you do, you'll know that it actually is what the tape says it is instead of thinking it's at 10* when it's really at 6 or 14, depending on how far off your balancer was and which way it slipped.

Got it!

Again, thanks for the help.
Looking forward to getting this weekend over so I can get back to it...

OK guys.. I hate to do this to you.
But I am not quite sure how the vacuum is supposed to be addressed for setting the idle.

It normally idles pretty high. So before I can do the idle thing as part of the Initial Timing, I THINK I have to get it down to a 'normal' rpm range.

That being said I have what seems to be conflicting information.
Earlier in this thread, Shawn stated:

But in my other post (above, about the Holley carb), someone responded with this information:

Maybe I am not seeing the differentiation between just setting 'normal' idle and setting it for the Initial Timing....?????

What say you??

Pull off and plug the vacuum advance to set your timing. The reason you want to keep the idle speed low when you set the timing is because you want to make sure that the centrifugal advance isn't coming in early and screwing you up. It's doubtful that it will but it can happen so just to be sure, keep the idle speed low when you set your timing. Once that's done, hook everything back up and attack the carb settings.

Now where's that wedding bar?

Roger that!

I had the vac advance at the distributor plugged, but the line from the manifold was still open.

Could this be why I couldn't get the rpm below 1000?
(I think we discussed that somewhere, but I am in a rush... lol)

If you had and or have a port open on the intake manifold its a vacuum leak. Weather on purpose or by accident.

Just a quick update....

I survived the GD wedding (thanks to open bar), so that's a step in the right direction.

Right now it looks like i won't get back to the garage until tomorrow night instead of tonight as I had hoped.

First order of business - reconnect vac advance and set idle speed.
THEN, start the timing thing.

Um, well, I would..

Remove Vacuum advance, plug hose so no leaks
Set idle speed low as possible
Time engine (idle speed can increase or decrease with changes in timing, lower if it gets to high)
Re-connect Vacuum advance
RESET idle speed if needed.

Don't make this more difficult than it needs to be.

Listen to John's, and Shawn's advice. There's no conflicting info, they are both giving you the same advice.

John's step by step is exactly how I do it.
