Sounds cool. Do you have any pictures of this set up?

Sounds like a nice set up. Do you have any pictures of where it comes together at the transfer case?

EDIT: Forgive the double post. This iPhone app is quirky.

Got it started and drove around the parking lot. The tranny felt like it started in high gear.
Don't know how to adjust the 727 linkage.
Can't get the thing to start without giving it gas.
Can't figure out the timing. I'm a diesel tech.
The throttle keeps sticking around 900-1,000 rpm.

I need help. This stuff is Greek compared to all the diesel stuff I've worked on.

Oh and the oil pump has a hellacious leak. Yep, it's a Jeep all right.

Dont run it with the pump leaking if its bad. Wont deliver the volume you need might hurt it. Wonder if they hosed up the gasket between the filter receiver and pump front cover? Oh yah also check to ensure the oil pressure switches are all installed or holes are plugged off. Set the timing at 15 deg base. Disconnect the vac advance while your doing that and the break-in you can tune the vac advance later. If it stalls below 900-1000 then it sounds like a vac leak someplace or the idle transitions in the carb aren't working/setup correctly. Take both idle mix screws and gently turn them in till they bottom out (gently not to score them) and then back each out 2 full turns. (good starting point) Set idle screw so throttle is cracked about .030 if you look down the blades. At this point as long as the carb is internally good/new and there is not any trash inside it blocking transfer slots in the venturis (just below the throttle blades inside the front venturis) she should idle between 650-800 depending on your cam duration/lift. The idle being out of whack will also cause the start issues.

Hell if you were close to Austin TX, I would drop by with the wide band datalogger and jet kits. Dial it in would take about 30-45m to get pretty spot on.

I set the timing at 10* for now. Thanks for the tip about the idle screws. Completely forgot about those. It's a brand new carb so no worries there.


The pump is leaking a few drips per minute. It runs around 40 psi when driving and 25 at idle. I can't tell exactly where it's leaking. But it is for sure around the housing. I might throw a Bulltear midplate in and see what happens. I just hope it's quality is better than the dipstick that I got from them.

I still don't know if I should use intake runners and valley pan together to fix the coolant leak.

Got the transmission shift linkage, and throttle valves dialed in.

Don't drive it without adjusting the throttle modulator for the transmission first. You'll burn up the trans quickly. Google can get you to a webpage on how to adjust it. I know I've seen one on www.ifsja.org .

I already got it dialed in. Shifts great and holds gears like I like it.

Hope so. I took my sweet time on the valley pan and didn't force anything this time. Cleaned it all up really well and used high temp rtv strategically. I'm letting it sit two days before I put the coolant back in and run it. Hopefully it helps it seal up well.

Now I just have to get the oil leak figured out. It's not horrible, but its dripping enough to be annoying. It seems to be coming from the oil pump. I am worried I might have screwed it up trying to prime my pump without petroleum jelly in there. I just spun a drill on high with the old dizzy for about a minute before it started pumping.

Return the pump and get a new one?

It's an AMC motor. The pump is a part of the timing cover...

I know that!! I thought it was replaced during the build? Probably still a warranty??? Pretty goofy system if you ask me, my chief has the 258 so I have nothing to worry about

The gears were replaced. The pump is original. I am not sure if its leaking from the idler shaft, the gasket, or somewhere that I can't see without taking my alternator off.

All you have to worry about is keeping up on the interstate lol.

mine leaked until i put in a midplate for the pump when i noticed a bad gasket. i added this midplate and my oil pressure went up a fair amount: http://www.bjsoffroad.com/prod-605.htm
