1990 YJ Carb Problem?

[jaspercomp]

Hello all,

I've seen quite a few posts related to carb issues with the 4.2 I6 from the YJs. our issue is a little different and we were wondering if someone has seen it or has a fix. Basically, the jeep is what we used to call "cold natured" it won't start in the morning without a shot of starting fluid. it cranks right up after that and you can run it all day with no issues at all, in fact, once it gets going it starts as soon as you hit the key! it just seems like overnight something happens to it, but not sure what! It has a gazillion connections, vacuum lines and other things attached to the carb. thanks in advance for any suggestions!

Should be a choke adjustment

Ditto. Choke probably stuck open OR the fuel filter doesn't have the return line in the 12:00 position.

Thanks all! i was thinking it was the choke as well, upon further inspection, the previous owner seemed to have the same problem and rigged a manual choke cable rig of some sort. it basically was stuck full open all the time.
