Works every time!

BUT! If I need to set it on for the emissions sniffer, I have to lean
it enough that the beer will start growing bubbles on the side of the
bottle for the sniffer to like it. The long 6 is supposed to be a bit
of a 'thumper' engine. It needs bubbles in the beer to pass....

If it just purrs at 750 rpm, it will be running a bit too rich for the
sniffer.

Yes autozone should have the kits. Just a basic Carb Kit. They come
with all the gaskets and a new float needle and seat and a new
accelerator pump.

The linkage that gets sticky is the plastic step thingie that the choke
uses for the fast idle. It just plain gets dirty on the pivot point.
WD40 is a good cleaner, but a carb cleaner spray is better, the real
cleaner doesn't leave junk behind to attract more dirt.

If you don't have to unscrew some of the parts to clean them when
installing a kit, then DON'T!

A lot of the adjustments given in the instructions for the kit are not
needed. Most of the carb can come apart without unscrewing settings
just to clean it.

Some things you must unscrew like the idle Jets, but you just count the
turns as you screw all of them in tight 'before' screwing them all the
way out. That way when you put it back, you just screw it all the way
tight again and back off the screws the same as they were.

As you commented, it worked great a year ago, now it is time for a clean
and it will work great at the same settings as last time it was cleaned.

Trying to mess with settings to make up for dirt is a big pain in the
butt, it will never stay stable and isn't the right way to do it except
for a trail fix to keep you running.

I wouldn't mind trying to help you put a kit in it via email. I do have
some photos here showing the parts and what not to mess with or I can
take a digital photo of some directions I have here to refer to.

Re: Carter carb replacment
 
Okay Mike...just was out checking things out. There are no drops of fuel
spilling over from the two venturi nozzles. I messed around with the high
idle cam and curb idle screws (think that's the proper term for them) and
finally got it to sit off the high idle cam and rest on the curb idle
screw...set it correctly and everthing is great rpm wise. It still doesn't
idle completely smooth....but foam won't roll out of a tall neck that's for
sure!
I'll have to wait until it's cold to see what she does now. It used to never
want to jump off the cam to settle in the curb idle.
The other thing I'd like to do eventually is get the O2 back in the loop but
I have absolutely no idea where that thing hooks up to. There is a huge plug
connector right off the O2 sensor that still remains but I can't locate the
other wire that would have the other half of the connector on it. Any idea
where this wire/connector comes from? Pictures would be great,...my Chiltons
sucks @$$!
Thanks again!
Allen

Re: Carter carb replacment
 
Okay Mike...just was out checking things out. There are no drops of fuel
spilling over from the two venturi nozzles. I messed around with the high
idle cam and curb idle screws (think that's the proper term for them) and
finally got it to sit off the high idle cam and rest on the curb idle
screw...set it correctly and everthing is great rpm wise. It still doesn't
idle completely smooth....but foam won't roll out of a tall neck that's for
sure!
I'll have to wait until it's cold to see what she does now. It used to never
want to jump off the cam to settle in the curb idle.
The other thing I'd like to do eventually is get the O2 back in the loop but
I have absolutely no idea where that thing hooks up to. There is a huge plug
connector right off the O2 sensor that still remains but I can't locate the
other wire that would have the other half of the connector on it. Any idea
where this wire/connector comes from? Pictures would be great,...my Chiltons
sucks @$$!
Thanks again!
Allen

Re: Carter carb replacment
 
I replaced the Carter carb. on my '90 YJ 258ci about five years ago....the
Weber carb. has run much better in my experiences. The vacuum lines that
are no longer used simply get plugged, but I think I only did that to only
one or two vacuum lines after my conversion.

In fact, it was this very group that I found a seller, who just purchased
the EFI kit, and let the barely used Weber go for almost 1/2 of retail cost.
