Bring it over and we can rebuild it or buy a new one or upgrade you to a different carb.

I'll look through a crate I have full of old carbs as well. I may have something you can salvage for parts. Is oe a motorcraft? I'm not to familiar with AMC stuff. Also I believe it is a 2 barrel. Let me know and I'll take a look at what I've got.

It should be a standard 2bbl motorcraft.

Ok so I hooked up the freon to it and had the ac set to high recirc temp to lowest. The clutch was engaged and the psi said 35. I added freon and the needle stayed at 35 clutch still engaged. I felt the ac out of the vents and it was cold this time. I kept adding freon and the clutch never disengaged. I turned the temp up to 77 and the clutch still didn't disengage or cycle. I put a little more freon in and while the can was hooked up it stayed cold but after I took the freon off the air coming from the vents warmed up a bit even on the lowest temp setting. This makes it seem like there is a nice leak someplace. The ac lines were very cold to the touch.

Keep in mind that adding freon is a temp fix and you risk blowing seals. To do it right you need to have a vacuum setup so it does not have pressure when it is not running. This is the only easy to properly remove sure from the system

I got lucky and ran into a Jeep mechanic of 25years at the auto store that overheard me talking about the ac. He had great taste as he complimented the 5.9. According to him everything under the hood was working correctly and that the issue was with wither the ac controls or the blend door.

Except now you have an overcharged system. It's generally a bad idea to add refrigerant to a system without knowing exactly what your pressures are. Unless you have a manifold gauge, and/or a vacuum pump, you shouldn't add refrigerant. Most people who talk about freon leaks or being low on freon generally don't know what they are talking about when it comes to refrigeration systems.(sorry guys who used the term freon, I said "generally" so as to exclude present company). I won't pretend to know a lot about the ac system. You need to know how much refrigerant is supposed to be in your system, then evacuate it and start fresh if you don't have gauges. However you would also need to pull down a vacuum before recharging. Long story short, if it was blowing cold, refrigerant is probably not the issue. I'm sticking with blend door/s. they are notorious for failing in the Cherokees and Rangos. I have to do mine, but I'm going to find the aluminum ones. BTW, it's a serious PITA to do. The entire dash has to come out, heater hoses an ac hoses get removed, etc. I have the manual for the Rango, if you wanna see it, it should be very similar.

The difference between stupidity and ignorance. Ignorance is doing something wrong and not knowing better. Stupidity is knowing better, but doing it anyway. Don't be stupid!

I was using a gauge to see the PSI but either way it's blowing cold for now. Anyone been to the Hofbrauhaus? I am being drug there tonight for the wife's extra curricular work related get together.

It's very loud and obnoxious. It sucked! At least I didn't enjoy it. I was hoping it would be like "alpine village" that closed here years ago.

Sounds like a job for Marn. He's seems pretty dang good with his FSJ. He had that big B humming pretty good if I remember it right. Tuning carbs is a dying art. Not many people even attempt to learn about them. I'm no expert but you'll learn a lot.

Well, I like German polka and big cleavage so maybe this will have some good points.

it should just run if you rebuilt it right.

Not feeling well, so I need to take it easy for a while. I think it just might be this change of weather. Sucks that we didn't really get a winter this year. Maybe I'll get to see snow next year.

I won't be making it to the lake this weekend. I thought I got caught up with posts and I still don't know exactly where everyone is meeting. Calville Bay?

I already know how it will play out. Only half the people that say they'll be there will show up. On a hot day at the lake, all of them will refuse to take off their shirts.

Have fun, be safe and try not to sink your Jeeps.
