"We just purchased this jeep. It ran when we were looking at it, and starts like a dream when you spray starter fluid in the carb, but wont stay running long enough for us to even drive it around the yard. We are new to Jeeps and have no idea where to start. Someone we know suggested replacing the whole carb but is that necessary?"
So you replaced the carb on it and it now cuts out while running after a fairly extended period of time.
Does it start to sputter and die?
If it is carburated then there is probably not an electric fuel pump most likely it is mechanical. But if it is electric I would check to make sure it is not overheating during operation.
Would you mind purchasing a vacuum guage and connect it in the vacuum control system. You should be able to place a tee in the line to the vacuum motor for the 4 wheel drive. Should be on the manifold. Run a line through the firewall so you can watch it while you are driving. When it is running at a hot idle see what the guage reads and if it fluctuates. When you start having a problem then definatly watch what the guage tells you.
