I have checked by feel and by ear. It's getting dark now, but I'll try to check with some starter fluid. If it was a vac leak, what symptoms would the car have??

Sterling

I think it's your dashpot. Time for some WD-40!

Try shooting a picture of the side of the carb from the driver's side.

Sterling

In fact, just take it off. It's in your way anyhow. (It's for sissies anyway.)
If you're not going to remove the rod right now, then put a small washer on it (there should be a metal one or a smaller version of the plastic part), then the spring, and then put the white plastic part on upsidedown. Slide it down the shaft so you can swing the shaft back into position, and releasing the plastic part should keep it basically where it should be.
-At least you'll know that the rod isn't hanging up on anything when you work the accelerator.

Sterling

And please remove the air cleaner assembly when you snap the picture?

Ok here is a series of shots that should show as much as I can get to.

The images run from 66 to 71. 66, 69, 70, and 71 are probably what you need.

I humbly await your expert advice.

Oh yea almost forgot, the hot start cable is disconnected. Thats the loose one hanging off towards the firewall.

I had to type in the photo numbers to see them.
I see your idle altitude comp valve hose looks like it's busted. (The white one on the top.) That'll cause high idle! Both T-body nipples that go to the IACV, as well as the IACV nipples themselves need to be capped if you're not using it. The idle comp circuit snakes in throughout the carb and leaves about four places for vacuum leaks if not properly plugged. It'll probably be easier to reconnect it with new hoses than to try to disable it. But from the photo, it looks like that white hose is floppin' around.
If that is busted there and all else is in place with regards to that circuit, then plug that hose and where it goes and see what happens.
Also, you have not sprayed down the linkage with WD-40 yet. You really should. I did notice that the dashpot piston is further in than earlier photos, so maybe it's closing all the way. This means ********, er I mean cdrad51 is right, and it's probably a vacuum leak.
Let some slack into your choke cable, too, just for now. If it's too tight, it pulls on the fast idle linkage. If you slipped and put wieght on the carb somewhere, you couldv'e bent a bracket ever-so-slighlty to cause this condition.
If you have not messed with hoses, etc, then it's possible (though unlikely) that you could've had a vacuum leak that was plugged with gunk and you shook it loose. (-Like I say, not to probable.)

Take a look at your OMP rod, too. Make sure it's not hung up on something. Make sure that the secondary throttle shaft closes all the way, too. Enough dirt in the linkage, and that could actually be your problem.

Thank you cuckoo case, and happy new year to you too!

It's been said many times before, but Sterling.. You are a genius .. All I see when I look at thos pics is some really dirty parts.. LOL

nevarmore

Actually all the white/translucent hoses are intentionally disconnected. When I was replacing vac hoses I decided that 20 year old plastic couldnt be holding out any better than 20 year old rubber and just ran new hose instead of using those.

Aside from that I will slack up the choke cable and hose the whole works down with some WD-40.

Hopefully that will clear up any issues. Thanks for your help everyone!

Sterling

I am not. You're just giving cdrad51 more to pick on me about!

nevarmore

And making me feel bad about having a dirty engine bay!!

cdrad51

He's just an overinflated ego who's head is now ready to explode!

Hi Sterling how's that for picking on you?

Sterling

Hmmmm.
So how's that jet configuration I PMed you workin' out for ya?
-Or did you blow all your pocket change on Cheetos, you fat frugal lazy bastard?

partsguy74

Nevarmore, my car's engine bay is not much better (not picking on you).. Just making the point that anyone who can look at a couple pics and give that much of a detailed diagnosis, is amazing, in my eyes..

nevarmore

OOk. I greased the sumbitch up with some WD40 and loosened the choke up a tad.

Still idles at 1500, smoother now. When I went TO work it still felt a bit off at lower RPMs, bucked just a little bit. On the way home, it went back to stalling from time to time.

My gut is telling me that its the combonation of a vaccum leak and a terribly misadjusted linkage. It runs well enough to get me around until I can find the time to really tear into it.

Thanks for your help everyone. I owe you guys some beers.

Last update here. Its fixed now.

Guess what kids, karma is a bitch!!!!

Peejay comes down (thanks pete!!!) leans over my car, feels around for 30 seconds, and comes back up with a split hose. He cuts 1" off the end of the hose along with a small piece of his finger, puts it back on, and the car runs exactly like it did before.

It took longer to go around the block on a test drive than it did to fix. We both think it was totally circumstantial that it broke when I was futzing with other parts of the car.

cdrad51

Way to go Peejay. Props to you.
