I'm fixing up a '78 CJ5 and for the life of me I can't find the name or the part online to replace. If you lift the hood and look at the carb it will be in the back left corner of the carb. It's almost like a fuel line, it comes off one spot in the carb and bolts into the engine block and the line coils back and connects to another part of the carb. I can posts pictures if I need to, I'm sure someone knows what I'm talking about, thanks!

Would the engine run with this broken? When I was removing the carb, I took it out and saw that the tubing was pretty much charred black since part of the tube going into the engine block had been broken off.
Cull that piece of junk for a manual choke. You can find them at the auto supply house.
The same auto supply will carry hot air choke repair kits. I've seen them on the shelf at most NAPAs, and OReillys. Its Dorman part# 76850.
I only mention it because I went the same route. 5 years ago, I had a rotted out hot air choke that didnt work. The problem is that they default to CLOSED CHOKE when the tube is broken, which fouls out the engine....
So I installed the manual kit. Easy enough to install, works when used properly. But the problem was I was always forgetting to turn it off.. or turn it on.
I struggled through that for a year, then realized you could get the hot-air choke kit for $10 or so. It works beautifully. I never worry about it. Jeep starts right up, even sub-zero. Choke works as designed.
If its stuck closed, it would foul out while driving, then be very hard to start sometimes. You can look at your plugs. Are they pitch black and sooty? Likewise, if its stuck open, you might need to pump the gas 20 times before it starts up. The chokes can be a pain in the pain, and responsible for all sorts of gremlins... but once you get them working well, its almost like a modern car.. lol. "almost"
I believe it was stuck wide open but the jeep wouldn't even start. It would crank over and only keep going for a short time with some starter fluid in the carb. Then at the end when it would die out it seems there was a loud whining type noise coming from the bottom of the engine.
