I did check and replaced the plugs. I took each wire off and it is firing on all four. As for the carb. it looks like it could use a good cleaning and maybe a rebuild so maybe I will try that first. The fuel pump that is on the jeep now is a small one with no vac. I do have a larger one with the vac. at the bottom that I would like to place on. If I was to change the fuel pump and for now just plug the bottom to vac. ports that should work right? Thanks for the help.
