And does it affect my idle?
Manifold will increase your idle but you make the final idle speed adjustment after you set the timing with the hose disconnected.

Port vacuum will not effect your idle speed. Or should not.

That's not your idle speed problem right now.

Vacuum advance port can be decided later. I've run them both ways.

So for RIGHT NOW - setting the initial idle, having the vac advance connected to manifold vacuum is correct?

Once I have a decent idle speed I disconnect vac advance and set timing.
Then reconnect and readjust idle...
Does that sound right?

Sorry if I sound like I am getting confused again. But I am...

I would set the idle speed with the vacuum line OFF

Set timing with vacuum Line OFF.

Put vacuum line ONN and reset the idle if needed.

Got ya.

Now as far as my current timing at 7*....
Leave it there for setting idle, or no?

Is there any chance the throttle cable from the pedal is holding the primary's open?
Will it still idle a 1,600 with the cable off the linkage?

The only other time I've had a hi idle issue was with a BBD and sticking throttle plates.

I've tried disconnecting the cable, with no luck....

Your a real trooper. I would have chunked that carb along time ago. Seems like a real pain in the a$$ to do adjusting on.

Stubborn, is more like it... lol

To be honest, it is mostly my inexperience with carbs/ timing that is the problem.

We'll call it "persistent". You'll figure it out.

One thing I am still unclear on is where I should have my timing set to start this whole process over again.

With it where it is at 7* with no vac advance, it idles high - as we've discussed.

Obviously, I can get the RPMs all over the map my playing with the distributor. The closer to '0', the lower the RPMs....

Just don't want to tamper with the carb if I should back off the distributor....

Thoughts/ recommendations?

Wheel, Fix, repeatů.

With my distributor (junkyard motorcraft out of a Grand Wagoneer) I set my timing as per factory (8*@1600 then checked it at idle of 600 with no vacuum advance) and at idle with no vacuum advance it still shown 7*. I say don't sweat it. Concentrate on your high idle and leave the advance unhooked for now.

I thought for idle that transfer slot measurement was a do not exceed. But its been a while.

The FaceTime offer still stands. Then I can see exactly what your doing. I'll be at work tomorrow by 6pm. No trouble calls ill answer the phone.

Ok, we're all missing something really stupid. This ain't right..

Here's what I do in similar situations. Get your favorite liquer (price is a non-issue at this point), Relax alone, if possible to this and I can nearly promise you that it'll come to you.

Laugh if you want. It works

Live in a way that those who know you but don't know God will come to know God because they know you.

The .020" is called out as a dead-on measurement for the primaries.

And (from what I can gather) not-to-exceed exposure of the slot for the secondaries.

Good stuff, right there!

Wasn't able to get anything accomplished last night, except re-tightening bolts (surprised how loese they were after just one heat cycle ), and fogging the entire engine looking for leaks - still none

I did spend a good chunk of time trying to figure out why it would only crank and not fire all of a sudden..... turns out I knocked the feed line off of the fuel pump when messing with the distributor hold down bolt. What kind of PO doesn't put a CLAMP ON A FUEL LINE????

I was unsure of how the current timing thing, so I didn't go any further. Probably should have, but wanted to be sure the information you guys had given to me took into accout the current timing of 7*

Anyway...
I think, my current confusion is a chicken/ egg thing:
Do I lower the idle by carb tuning, then set timing, or use timing to bring idle down (adjusting if it won't go far enough).

After reading and re-reading, I THINK the plan is:
Keep timing where it is at 7*
Pull carb and adjust secondary throttle plates per our discussion above (pert' near closed)
Then set overall idle speed

God, I hope that's correct.....
