Help Jeep wont idle
I have the dreaded jeep won't idle problem. So I have a remanuf jasper 258 with non feedback carter carb. Team rushed then ignition nuttered recently with no problems after each. Motor was running pretty good up until a couple of days ago. I fixed a leaking mechanical oil gauge fitting. Jeep was idling fine. Then noticed the TAC door flap was closed so I started looking into the vacuum lines. So I guess I still have a bunch of crap vacuum lines from the emissions stuff still hooked up, not sure it is right due to not even having a feedback carb when I bought it. It was hooked up to one of the vacuum solenoids on top of the valve cover since I didn't really know where it went at the time and it worked for a while. So I decided to try to find a place on a another line and t in. I did and when I restarted it worked. I then started looking at maybe cleaning up some other lines so I disconnected the line going to the 10" vacuum switch and capped it. Restarted and would not idle now. I thought I put it back together the way it was and still the same problem.
So I went to start it this morning and it cranks right up, with choke on and runs good until choke is about almost off and engine is warm, then sputters and dies. Will run good as long as I is above 1500 rpms with the gas pressed. Let off the sputters and dies.
What the heck did I do? Did I pull something off important when I removed the TAC to get a look at the carb and tug on the vacuum lines to trace them. I didn't make a bunch of changes all at once and I thought I got it back together the way it was after. Now it may be just in my head but I did have a slight sputter earlier in the week one time and it did seem to be slightly more rough when cold- this week- but the choke seemed to be coming off quicker than normal- maybe because it has not been as cold? But surely since it was running ok minutes before I have inadvertently done something? Any ideas to start with. I should have time tomorrow or the next day to really look at it, so far I have not, but I couldn't see anything but I was a little panicked and rushed for time when it happened
