cj stalling

the past three days my cj has been stalling out almost immediately when i come to a stop. whenever i push in the clutch the tach needle drops and it stalls out. i checked the carb, and the choke butterfly was sticking open. after i cleaned it, it shuts. however, when i was manually pushing the throttle the butterfly did not hardly open or close. someone please help. im not good with carbs and i believe this is the main problem. thanks.

Do a search here and on google with carter, stall, idle, etc.. They are famous for what you describe. Easy fix by drilling out the idle tubes a hair.

did you look for any vacum leaks take a can of carb cleaner and spray it around the base and intake of the carb and see if it idels any better the choke is springe loaded and opens and closes buy heat when hot it should be open when cold it should close when you move the gas pedal and you might havs some dirt in the idel circit of the carb might want to rebuild the carb and see if that helps

I have the 258 with the Carter BBl and I too was having it die at idel and any time I used the clutch! I first changed the fuel and air filters (was time anyways). Found that this did not fix the problem so I shot some wd40 around the vacume lines and found no change in motor noise (rpm). So I decided to remove the carb for a rebuild/cleaning.

NOTE :I am not a master mechanic but a brave weekend wrencher.

I followed the limited info in my hayes manual as well as looking up the carb link listed above. I tore apart the carb and soaked the mid section with the float bowls and used spray cleaner on the rest of the carb. I followed the drill out instructions for the idle pickup tubes and reassembled the carb. While I had the carb off, I tightend the manifold bolts (had a leak near the fire wall). replased all the parts and fired up the ole-Jeep. after a small warm-up she runs better than ever.

I found the info in the carb ling to be of great value and well written.... THANKS>

same thing is wrong with my 258. (Diffrent carb i know), but the choke plate would start out open then fall closed when i was driving, sometimes the only thing keeping it alive was the wheels rolling. My vacum system is all messed up and I'm vacum retarded. so if anyone has a diagram of the vacum system that sure would help me a lot, and hopefully daytoncj too.
