Help!!!!
 

I have an 84 Jeep CJ7 just recently purchased was told it had water in
the gas got it home drained the tank, still running very rough started
diagnosing problems started normal course of action, plugs, wires,
filters etc. Still running rough pulled plugs again 1 & 2 are lean and
3 & 4 rich and 5 & 6 are lean. Started again pulled one plug wire at a
time starting at 1 when 5 & 6 were pulled neither had any effect on how
it ran.

Re: Help!!!!
 

That sounds like plugged up idle tubes. Very common.

A kit for the carb is in the twenty buck range and does them wonders.

Meanwhile here is a link on doing the idle tubes. They actually need to
be reamed out usually. This can be done from the top without removing
the carb. You just have to remove the choke plate and the venturi will
twist and lift out.

One other thing is the intake manifold itself. It can need a retorque.
To test spray WD40 or carb cleaner along the manifold head seam. If the
engine stumbles you have a leak.

Thanks for taking the time to reply. It now has a weber carb on it
could this still apply?

Re: Help!!!!
 

That would still apply for the possible loose manifold and even more
possible loose carb base. They are sneaky and come loose easily.

Now that you have a Weber carb, what has been done with the gas tank
vent or charcoal canister? Is it still tied into the PCV system?

The gas tank vent or canister also has an air filter on the bottom of
it. When this $2.00 filter is blocked, it does the damnedest imitation
of running out of gas and really lean.

When mine blocked last time, I got a 50 rpm increase in the idle when I
opened the gas cap.

Has the mix been set right on the Weber?
