Great trouble-shooting advice IO. I did install a new fuel pump, but that doesn't mean I got it right. I will do as you suggested and check those things out, especially the fuel lines.
Yesterday afternoon, I did get do a little more trouble-shooting. I just got your post this morning, so I will try those things out today. Yesterday, I was thinking about your comments about the resistance in the carb vs the resistance in the overflow. I went to the Auto Parts Store and ask if they had the checkvalve that shows up in the diagrams that Sly sent me. Of course, they did not. I told them my problem and they suggested that I try a little universal checkvalve they had, that would offer some resistance in the overflow line. I have attached a picture of it. (this is actually a vacuum checkvalve) I pointed this out to the Auto Parts Guy, but he said it would work fine for what I needed. I went home and sprayed the B12 in the carb and let it set as you guys had suggested. I then attached the checkvalve to the top outlet nozzle of the filter (the 1/4" outlet) and then I ran a 1/4" hose from the checkvalve into a bucket. I wanted to see when I started the Jeep how much flow I would have coming through this checkvalve and whether or not the Jeep would run with this configuration. The Jeep did run and I had a small gas flow (probably about a 1/8" stream) coming out of this little checkvalve. Well, I thought, maybe this is good so I connected the outlet of the checkvalve to the return line. Jeep would not run when hooked up to the return line. Once again scratching my head, and then I noticed that when I had the the checkvalve hooked up to the hose going to the bucket, the valve was in more of a horizontal position, but when I hooked it up to the return line, I had a shorter hose and the checkvalve was in more of a vertical position. So, I took the short hose off and ran a longer hose from the outlet of the check to the return line. I also moved the check a little closer to the outlet nozzle of the fuel filter. These 2 changes allowed me to keep the checkvalve in more of a horizontal position like the fuel filter is. Guess what, I start the Jeep and it ran. I let it idle about 15 minutes but it was idling to high (around 1800 rpms). I wanted to back it down somewhat but everytime I got it around 1400 rpms or less, it would go dead. It was also idling a little rough at the lower rpms. Around 1800 rpms, it will stay running on it's own, but that's too high for just idling. The second problem I ran into was that after I let it set and idle for about 15 minutes, I shut it down and it would not restart. Acted like the carb was not getting fuel. I could pour a little gas down the throat of the carb and it started right up and it idled again about 15 minutes. I could rev the engine and it appeared to be getting plenty of gas. Now with all this said, my questions are:
1) Will this little checkvalve work and provide enough resistance for gas flow to go to the carb but also keep the pressure down, so I don't do damage to the carb (if there's not damage already)???
2) Why will it idle at 1800 rpms but not at lower rpms?
3) Why would it not restart? Why did I have to pour a little gas into the carb to get it to restart? After it started it idled fine, just idling too high.
One more little tidbit of info, when I changed my spark plugs and wires, I noticed one of the wires going to the distributor cap was corroded pretty bad (green) and the connection down in the distributor cap looked corroded and rough. I have a new distributor cap and rotor, but I have not installed them yet. Could this be contributing to the rough idling at the lower rpms?
