Carter carb replacment
 

My 83 CJ7 has given up the ghost on the carb. I'm pretty sure it's a
carter....anyway to definitively tell? Anyway..it's a 258 stock motor...the
only bad thing is the PO disconnected the 02 sensor during a YJ tub
swap..there are a few things I can't find at the moment when it comes to
wiring inside the engine bay. The motor runs great when tooling down the
road but I can't get it to idle right. The choke wants to either idle WAY
high...or so low it stalls.
Question is what carb would you recommend replacing it with and what do I do
with all this emissions crap like the charcoal canister....or does it
matter...I think there are a few hoses coming from the carb that have to do
with emissions. Any write ups would be great.

Re: Carter carb replacment
 

You have a butchered wiring and computer setup that is going to run like
crap until you get it sorted out no matter what carb is on it.

Stock the idle mix and half those vacuum lines and solenoids are
computer controlled.

With no O2 sensor, the computer is stuck in limp home mode which clamps
down on the mix and the timing advance.

I would recommend you at least put the computer out of your misery so
you can start to make sense of the rest of the system.

That Carter carb you have on there is a very nice carb when it is tuned
up and clean. Mine goes like a scalded cat with just an Accel coil and
stock everything else. (no computer) I get a nice 19 US mpg and she
will easily bury the spedo in 4th.

Carbs do take some tweaking to get them to run right. That goes for all
carbs, so if you can't get the Carter running, not likely you will have
any luck with any other carb either.

Carbs are also supposed to get a kit put in them every time you change
your spark plugs according to the CJ owners manual. Do you know when
the last kit went in yours or when the last plugs went in? Kits are
less than $20.00 and are easy to put in.

Too bad you don't live close to me. I have helped 3 people put in kits
and kill the computers in the last couple months.

Things like the charcoal canister, PCV, EGR and air filter flaps are all
needed parts you cannot take off. The rest is mostly junk.

Re: Carter carb replacment
 

Thanks Mike.
The funny thing is when I bought it in September...it idled excellent. I
mean the thing ran great and I was so suprised because I've heard horror
stories about the 258s. Now that the weather has gotten colder...the idle on
this thing is crap...mostly runs WAY too high and on occasion will click
down and run so low it'll stall. Even when it's completely warmed up...does
the same thing. And doesn't the Weber replacement do away with the 02 sensor
and computer?? Not sure on that one. I'm looking for the most simple swap
possible..the MC2100 looks a bit troublesome for a guy who knows jack about
carbs (ME!).
