258 DIES WHEN I COMES TO STOP WITH ENGINE COLD

i have an 83 cj7 with a 258 and the bbd carb. the problem i'm having is that the engine is not wanting to keep running while cold. i start it and let it run for about a min. in the mornings. then drive on the freeway for about a mile to the next exit. when i come to the light the idle speed goes way down and it usualy dies. but when the engine finnaly warms up it runs fine. i tries to figure out the problem this weekend. i took apart the carb and cleaned the inside out. then adjusted the carb and checked the timing. same prob. the thing runs awsome when up to normal temp. but until then it wants to die unless i'm on the throttle a little. please help

Re: 258 DIES WHEN I COMES TO STOP WITH ENGINE COLD

Same problem with my 88. Make sure that a)The choke is set correctlly. It sounds like it's going off too soon. Maybe look into a manual choke if you have altered the emissions equipment. b)The idle mixture screws are in far enough that the motor isn't to rich. If they are out too much (and it doesn;t take much) you get too much fuel and it won't vaporize properly until the engine is warmed up.

Anyone else?
