I'm really sorry, if I'm making a new thread if there is already something about this but this situation is rather odd to me and between this and dealing with my recent battle with cancer, I'm stumped and in over my head

 

I bought this sweet little wagon a few weeks ago, been getting it back to nice working order and it was running great. I took it for a drive for a couple hundred miles and randomly the engine just shuts off as I'm down shifting to stop somewhere. Look in the carb and it's full of fuel, okay so the float is stuck I figured. Fixed that, and it was running fine till I got on the highway and same thing happened again. The accelerator pump looked like it was on its last leg so I threw a new one in, checked the gasket which looked fine and clean. Started it, and it ran, but it was idling at 2500rpm. I took it for a drive down the street and then it started all over again not idling. But this time there's no fuel dumping into the carb. The car will drive without cutting out or backfiring, but it wont idle. I'm kind of on my last nerve after checking and re checking every hose and electrical connection. I could really use some of your wisdom right now.

 

one thing I am kind of concerned about was the choke never closes and the housing for that coil/element is kinda just rocking back and forth in its housing, it doesnt really seem like its functioning, and I don't know if that makes a difference.

 

Anything helps, thanks guys!

It's been a long time since I dealt with a carb.  Hopefully someone else will see this also.  You'll want to fix the choke, especially when it starts getting colder.

 

I'm not sure, but if there is a solenoid that prevents dieseling, and it's failed, it might cause shutdown at idle.  I had this kind of failure on one of my SPFI cars.  I got it home by feathering the gas pedal to keep it idling, but if I let go, it shut right off.

I'll look into it.

 

I was messing around with it earlier and decided to put my hand over the carb while someone was turning it over and Giving it gas and it started idling by itself for like 10-15 minutes.

And thank you!

Oh, yeah, if it's still cold, and the choke isn't right it will stop like that.

I'm having a similar issue with my carb'd 85 wagon, today I'm going to check the anti-diesel valve, might be worth a look

Well I managed to move the butterfly valve, before it wouldn't move at all. Closed it a bit and got the engine to idle but it was still running at 2500rpm.

Iirc, the choke valve and a high idle cam would be interrelated since you need both to keep a cold engine running. What is supposed to happen, is that as a thermosensitive spring warms up, the choke opens gradually, and the high idle cam backs off, eventually dropping to full open and normale idle. The spring was heated by 12v.
