1978 CJ7 Golden Eagle Cutting out - Video

[kennethlarkin]

Hi I bought this jeep in April of 2011 and imported into Ireland from the UK. I drove 100 miles from Ferry to my home town Galway with no problems however towards the end of the journey it started to miss every 10 minutes or so. The problem got worse over the weeks and Now it only runs for about 5 minutes until it cuts out. i have to leave it for a half hour or so to get it to run this amount of time again. If I start it straigt away it will only run for about 50 seconds.

I though it wasnt getting Gas so I though it as fuel filter so i changed the fuel filter, located back near the tank but the problem still persists.There is no fuel filter before my carb.

I have an electric pump which seems to work fine. I disconnected the line after the fuel pump and put it into a bucket and it seemed to fill it as quick as you can drink Guiness. This has been going on for months and I want to sort the problem myself. I will try for another month but then I'll have to pay to bring it to mechanic. I am attaching a video of it running. This is the longest is has run 10 mins. I noticed some smoke coming out the back of the engine around exhaust manifold. Also there is red oil leaking from under tranmission case area (only leaks when engin running). The carb looks new but not sure. Do you think its a carb issue, timing issues, spark plug issue etc.

Also the vacume lines seem to be cut and Im not sure this was intentional.

Please note I am not at all mechanical but want to learn as I have three CJ7 .

Thanks for your help
Ken

I would start by making sure all hoses are connected, it looks like your valve cover maybe leaking oil onto the exhaust ?

You could have some junk in the carb clogging it up as well

Check the ignition module that is located on the left inside fender below the overflow and washer bottles. Remove the three bolts that hold it to the fender and examine it for damage to the resin. If it looks melted or is very soft this is most likely you trouble.
The red fluid is Transmission fluid, find and repair the leak as soon as possible. Hopefully it’s only the cooler lines loose and you’ll only need to put a wrench to them. Until you get it fix keep a close eye on the fluid level.
It seems you have a number of leaks. The valve cover is leaking oil and your exhaust manifold seems to be leaking. This is the clattering noise you hear in the video. The vacuum lines have been butchered and it was deliberate. For now just make sure you don’t have any vacuum leaks.
Good Luck! Anyone with 3 CJ7s in Ireland needs all the luck they can get.

Nice video, my guess is the ignition control module, if it is hot to the touch, it is shot. But, I really don't have any experience with that pre '79 ignition. That is an interesting electric fuel pump. They seem to pump gas better than suck it from the tank which is a long ways away. The best location for them is below the fuel tank level like above the Transmission skid plate. They also lose performance when the fuel level in the tank gets low, a pressure gauge could check that. For a carb induction CJ a manual pump is the best way to go. It also appears that the hose for the egr is disconnected, they can help make the combustion chamber run cooler and help the valves from burning up. The low lead gas nowdays does burn hotter than the leaded stuff.
