Try and locate the fuse that controls your brake lights. If you have no service information inside an owners manual, remove each fuse one at a time to check for any burnt out. Do not switch any fuse locations, or replace any fuse with a different amperage rating. example, if you find a 10A fuse that is burnt, replace it with a 10A fuse only. If you cannot find any burned fuses, you should probly replace your brake switch underneat your dash. Your brake pedal will hit the switch, so you shouldn't have any problems finding it. It will be small and black

Sounds like u have a fuel problem. The engine is not getting the fuel it needs thats why when u spray the starting fluid in it runs then dies when it burns it up. check the fuel pump and see what kind of psi your getting.

Sounds like your float height is incorrect in the carb. Hopefully it is a new carb, and not a used one you bought off of someone. Used carbs are not a good idea unless you have the knowledge to rebuild one.

Go online and download an owners manual for the Jeep. It will give you the location of the fuse associated with your dash lights. Or you could start pulling fuses and looking for the one that is blown.

The starter could need to be shimmed . Check at the dealer parts dept.

if the 6 volts is not steady it can be the earthing, or a bad connection on the relay. if the relay is getting hot then replace this as this can be a problem when the relay is warn. clean all the earthing points and wires. this will improve the the electric flow. also if you don't have one fit a ***** strip wire from the body shell to the engine, this can improve alternator voltage, meaning better charge to the battery.

Likely you have a drive line issue. Universal joints and Constant volicity joints are suspect.

i would start at the ignition switch as thats where the power comes from to power up the fuses for these components, there are power wires from the engine compartment that come throught the dash in the center or rather come through the firewall, i belive its about 4-6 wires with a connector plug under the center of the dash, the connector heats up and causes a bad connection,start by located that first then check the postive side of the battery for a bad power wire connection if its not the main power wires that i told you about in the center of the dash, you can get to them from the driverside under the dash. let me know the outcome.
