Here's the latest information. We covered the access port under the stepper
motor in the carb, and it has no effect. With the air cleaner removed and
the nutter bypass installed, The '84 Jeep starts and idles just fine. The
problem comes in after the engine warms up. When the warm engine is shut
off, fuel keeps running into the carb for some reason. Then, with a warm
engine and the intake full of fuel, it's obviously flooded and will not
restart. The question becomes, why is this fuel still running through the
carb and into the throat? Our best guess is that the carburator float has a
problem, or a needle valve problem or dirt. It did not have am inline fuel
filter on it (it does now). Anybody have anything to add or other opinions?

Bad needle valve. Part of a kit you need. Probably replace the fuel
fitter too, that let the crap jam it up.

Overhalut the carbureator and install a new float needle & seat.

They sometimes call that vapor lock. The vapor builds up in the hot gas
line forcing the gas out of the line and in your case flooding it out.

To start, the needle and seat in the carb are worn badly likely. They
are 'supposed' to get a new one with a carb kit every time you change
the spark plugs.

Then you have to address the gas supply issue. Jeep uses a two outlet
gas filter in it with a return line to the tank specifically to stop the
problem you are seeing.

The center outlet on the gas filter goes to the carb and the top outlet
goes to the return line. It is important the return line is at the top
to avoid gas siphoning when it sits.

Your gas tank also has a vent line on it that leads to a charcoal
canister.

So basically you have 3 lines going from the front of the Jeep to the
gas tank.

Sounds to me like you are missing at least one of them.
