My 89 jeep wrangler is hard to start it has a carburator,I have replaced the rotor,dist. cap.plugs,and wires,and gave the carb. a good cleaning,and it is still hard to start?

How is the choke setting? What engine ? Try pushing pedal to floor once or twice before starting. Did that help? If not,remove air cleaner assy & have a look at position of choke plate, it should be close to fully closed if cold out, or partially closed, depending on outside & engine temperature. As engine warms up, that plate should gradually open straight up for normal running temperature. Are you experienced in that system at all ?

If it has a carb, then it also has a choke. Is it closing fully when cold and opening part way immediately after starting, then completing the opening cycle as it gets hot? Also, when you look down into the carb and quickly move the throttle, you should see a squirt of fuel...If not, the accelerator pump is not working.
Your problem can also be the result of improper ignition timing. If you have adjusted it are you sure you have it set correctly? (not saying you did this but I have seen timing adjusted retarded instead of advanced too many times not to mention it) Also on the subject of ignition...Is your spark healthy? You should have a nice blue spark that "snaps" when bridging a 1/4" gap, not an orange fluffy one. Ya can't start it if ya cant light it!!!
Some of this has got to help you...I've covered as much as I can think of!!!
