    YJ Vaccum hoses question

    That figures. I'm always a day late and a dollar short. Now some of my parts are even nonexistent. :)

    YJ Vaccum hoses question

    I looked and my red line doesn't actually run to the carb. It "T"s into a line from the manifold vacuum port under the carb. This may not be stock as my Jeep was very worked over when I bought it. The drawing is one I had copied from someone else's site. From there it goes to the transfer case...

    YJ Vaccum hoses question

    "A" is a switch that turns on the 4WD light on your dash when you pull the tcase into 4LO or 4HI. "B" looks like a vacuum check valve. The blue wire is probably a vacuum line. "C"-- I have no idea. Unless this was the previous owner's way to fix a vacuum leak when he disconnected lines. "D"-- I...

    weber carbs

    That makes sense. Mine seems to start fine after I crank it a while to get the fuel built up. I'll check their stuff out on JU. If you do find that was your problem, post it and what you did to fix it.

    weber carbs

    I found a used one and rebuilt it. My experience was a little different. My mileage went from 15 - 16 down to 12 - 14. It is also somewhat hard to start after it sits for a day or so. I've found that if I pump once to set the choke, crank it for about 15 seconds, pump it a couple of times, then...

    what year engine is in my jeep yj

    That's a day build code. I have lost the link to a site that breaks that down. I posted a list of pre 1987 casting numbers on your other post. See if you can find that casting number on your block. It may tell you more. Is the valve cover plastic or steel? The original 87 has a plastic valve...

    AX15 expert needed

    I tore down a donor 89 AX15 to see what was needed to repair. One of the items is the counter 5th gear. No problem there. What I need to know is about where the shaft that counter gear is on goes into the rear housing. Is there some kind of bushing that needs to be there? There has been some...

    Motocraft 2150

    I wish you better luck than I had. I tried for 2 weeks to get the 2150 running right and finally sold it on ebay and put the Weber back on. It may have been that the carb was too worn out to be rebuilt. Whatever it was, it had to be something strange on mine because I've heard too many that...

    AX-15 questions

    Where did you find the aluminum slave? I'm rebuilding a 231 and ax15 for the same swap.

    Motocraft 2150

    The ones I found didn't have 2150 stamped on the carb. All they had was a tag with a number to cross to whatever year, motor, and vehicle type it came from. If you stick to the early 80s and a small V8, you should be ok. Like wm69 said, some V6 motors had them too. Look for an early 80s 302 and...

    Transfer case question

    Not really a problem that I know of. It is side to side at the point it contacts the 3 low range gears within the planetary. I can't see that anything is worn on any of the gears. The movement is very little, but I want to make sure it is within specs as close as I can. It's just something I...

    Transfer case question

    I'm rebuilding a NP 231 to replace my 207. It's torn down now. How much play should there be between the input gear and the planetary gears?

    EGR Valve?

    Are you using the port to the rear of the carb? That is the right one. If so, your EGR valve, CTO switch, or cannister may be malfunctioning. Any of those could act like an open vacuum source making the motor die. If you are hooked up to the front port on the carb, it is a constant vacuum that...

    EGR Valve?

    I've got an 87 with the 4.2 and a Weber 32/36. The EGR was disconnected when I got the Jeep when it had a Carter, and I left it disconnected with the Weber. No rough running problems or anything like that. I haven't been able to get it to quit running rich though. I am wondering if the...

    No more 4th gear

    I hope you have better luck than me. I have an ax15 I'm waiting to rebuild. I don't want to even start it until I find an affordable 231. Affordable seems to be the hard thing to find.
