I have a 1987 jeep wrangler that is not running. I thought the problem was the old stock carb. I am installing a new upgraded carb but having a problem. The jeep always needed fuel injector cleaner added to the gas (fuel filter is new) or it would buck. It also had a rough idle that would buck as if it was not in the right gear even though it was. It would not start in very cold weather and that is how it ended up not running. It was very cold and would not start then we had a warmer day and I was able to start it just long enough to pull into the garage. the new carb is half on. I am at the point that the instructions tell me to start the jeep and run for a bit and then mark the vacume hoses but it wont start. (almost did) but after a few tries the battery whent dead so i took out and used the battery from my trooper and after a few tires that too when dead. I charged them overnight and same problem dead dead dead. Do I have some other totaly diff problem. that it was never the carb and maybe the alternator ? It did run it did turn over befor? any ideas?

hey kathy,i am pretty sure the instructions should state to mark the vacume hoses before you took old carb off(so you knew where to install them on new carb). because the eng. won't start with too many open vacume sources. how the plugs look(fouled?) yoy may have a weak ign. sys.(coil/wires/cap/rotor?) make sure pick up in dist is clean(no rust) you have to ck. the timing(suonds like it might be an issue also) but ya gotta have it running to ck tje advance,oh yeah ck. the vacume advance on dist. also. hopefully the vacume lines will kind of lay where they need to be otherwise,get a book on that veh.,or try to find a vacume diag. under hood some where. good luck let me know what you find.

Well you are right about marking the hoses before hand and I did do that. They only say to mark/check them again to be sure it is correct before going any farther. I had a thought about the timing too before it died. I thought the belt may be loose/stretched? At this point I am just hoping there are too many open vaccume hoses like you said. I will look into the other things you mentioned as well and I have a book on order!
Thank you for your help,
