I suppose you could plug the rest and it will run but not sure it will run at its best. I would not run mine that way, but if you have to thrn run the distrubutor to the manifold vacuum, and the fuel vent from the carb to the canister.

Yes, I have Bagusjeep and Puthijeep set up that way.

Just a simple 50c length of hose from the carb to the distributor.

It will run absolutely fine and you can eliminate all other sources of issues with the engine before you add more complexity. Later on you can think about the tank vent, crankcase breather and all the other stuff that I have never connected.

With the other connections on to the carb that are currently open you can plug them by fitting a short length of the same hose but with something rammed in the end of it to stop it leaking. Some people use golf tees, ball bearings. screws, small bolts etc or the hose is just folded over and tied. They are temporary and easy to take back off.

Alright, I cant seem to get my buddy to come over to help.... so I guess its just me on this project. I have tried looking at diagrams for vacuum hose routing, but i get sooooo lost. there are so many things that are on the diagrams that I am missing so its hard to get it back right. I know if I do the nutter bypass, it will eliminate a lot of hoses, but how about I dont even have a CTO valve, so how would I go about doing the nutter bypass?

Chuggins08,

Go to this site.

Figure out which vacuum systems you still have, and those that have been eliminated. I'll give you a hint, yours have been stripped down considerably.

Once you know what you have, and what you want to keep or add, then we'll talk about how to hook it up.

Follow the diagrams I posted in post #7. All you need there is EGR, Canister, PCV on top of the valve cover and distributor, which you have. You have posted pictures of all that in your orginal post. Now for the CTO there are usually two types a 2 port or 5 port. My 84 has a 2 port which is in the picture below. It should be on the intake manifold below the carb. If you are looking at the carb from the drives side it will be to the left of the carb.

Yeah on mine, it's like the PO bypassed it and put in a bolt instead

Hmmm. Perhaps someone here can help you with one. Not sure if you can buy them new. I remember there being a discussion on that sometime ago. You may find on at a pick and pull on and old AMC car.

Most auto parts stores will sell a 3-hole CTO, if you can't find a 2-hole. Just cap the top hole, if you don't use all three.

This may help with a new one. It is real name Ported Vacuum Switch. Only Jeep calls it a CTO http://www.drbob.tqhosting.com/tech/cto.html
I think you need the 115* CTO as noted here.

This one may work.

FYI, I just bought the Borg-Warner EC970 3-port to run the signal for my charcoal canister. It was black, not red, as the chart above indicates.

Good luck.

I don't have one, just a single hose from carb to distributor.

Seriously, start off simple and get the engine running first, then worry about the mysetries of AMC vaccumm lines.

Alright, I've got a hose running from distributor to carb and plugged the rest. Do you think I would be better doing the nutter bypass? Could I still just have one vacuum hose hooked up with the rest plugged?
