It will happen! Your jeep, your baby, your pride and joy will fail to start. It has to be that no account carb again! @#@#@5, dadgumitall! You just replaced it a month ago and already it is all farbed up.
Chances are there is NOTHING wrong with that carburetor and that should be the LAST thing you check in attempting to diagnose what is wrong with your jeep.
As pictured above you should start with:
Sparkplugs
Battery/Ignition Cables
Distributor
Ignition Timing
Valve Clearance
Carburetor
It's important to work through the steps and systems to ensure that you locate the source of the problem.
