Re: 83 cj7 idle
Welcome to the world of jeeps! these are the usual symptoms of a Jeep. What do you have for emissions stuff on your engine? the following tips are for a 258 I6, I am assuming you have that.
First, give it a thorough tune-up, ie: new plugs, gapped to .35, adjust timing to 6 or 7 btdc, new wires, if needed, change the oil (just b/c you should) and spray some carb cleaner all over the inside and outside of carb. after you have done this, and it still idles poorly, and i expect it will, try cleaning out the venturis in your carb. they are notorious for getting clogged up. it is a very simple procedure, and terry howe, i believe, has an article in the tech section of the jeep section of off-road.com that will give you a step by step on how to do this.
As for pumping it like crazy in the morning when cold? that isnt too uncommon. 3 or four pumps should do it. once it starts, you may need to hold your foot on the gas for a bit until the engine gets a little warm.
Hope this helps!
