Hot idle miss

[Skeeter74]

I still have a miss, which I thought was the motor loading up but now think it may be lean. It only does this if the motor is fully warm and idling for an extended time, like a drive through or a long light. Coming off a 12 mile run at 65 mph will not cause the miss, it takes running around in town in stop and go traffic and I have not been able to reproduce this idling at my house.
After 10 minutes or so of low speed running in town, I pull up to a light and for about 10 seconds it idles smooth. After that, it will start with a small irregular miss and progress to a serious miss and stumble. When the light turns, one hit of the gas and I am off and running just as pretty as you please. I intend on ridding myself of all extraneous vac and emissions lines. Any other thoughts? Maybe EGR?
Any help is appreciated.

Sounds more like the carb inlet needle isn't shutting off the fuel flow when the carb bowl is full or the venturi drip. In other words, your getting flooded at low speeds. When was the last time the carb was rebuilt/opened up?

I'm betting if you pull the aircleaner and look into the carb throats when it's doing this you'll see fuel dripping from the venturi. There's a detailed post on clearing up this "drip" as well, just search for it.

just rebuilt a month or so ago, but I will check. The hard part is getting where I can work on it while it is doing it. It seems to be home sick, as when I get home it quits.
