Weber Carburetor Conversion Jeep CJ YJ Wrangler 72-90
 

I have an 88 yj, with the carter 2 barrel, the carb is getting a little
worn. The conversion is listed on ebay. I am wondering if this is a good
conversion.
Thanks for any input.
Mike if you see this I would sure respect your opinion

I believe Mike will tell you that you can see the same performance by
tweaking your stock Carter carb in two ways: the Nutter Bypass and the
cleaning of your too-narrow idle pickup tubes. I'm sure others in
this forum have plenty of links on each.

I had the weber kit on my '88. It ran a little smoother, but I didn't
really feel a big difference and i saw a 2mpg drop. I put my Carter
back on a few weeks ago, and after the aforementioned tweaking, I'm
really happy with it. Not to mention that cleaning the idle pickup
tubes will cost you less than $5 for a can of carb cleaner, and the
Nutter Bypass, which eliminates the computer, only runs you the price
of the wire you have to run. The Weber kit is, what, something like
$400?

I will agree with the other poster, the BBD can be made to behave. A
carb kit is easy to put in and runs in the twenty buck range.

To swap out for the Weber, you still need to get the computer out of the
loop because it goes into limp home mode so I would recommend the Nutter
bypass first with a carb kit and the idle tube clean and ream.

If you go that route, there are a couple tweaks on the 'nutter' I use.
I use two new wires rather than mess inside the harness, especially on a
YJ which has different color codes than a CJ.

I also set the stepper pins in the center of their travel for the high
speed mix, not full rich like the Nutter directions say. That only
allows a good idle mix setting with crap for mileage and top end. My
way gets in the 20 mpg range highway.
I stayed with the stock ignition also, I just went with a hot Accel
'SuperCoil'.

Sometimes is is to just go all new though....

Umm, that should be 'Sometimes is 'nice' to just go all new though....'
