I think that I have nailed the problem. I took the intake hose off the carb and it sprayed gas about 3 feet. It turned out that the brand new, 2 weeks old, fuel filter was not working properly. It is a see-through fram designed for 3/8" rubber line. I have used these filters for a year now and replaced several of them. I have a filter, new, in the tank and another one just before the carb. The one before the carb always gets clogged. I think that the rubber patch lines, new also, are letting black deposits into the filter and clogging it up. At any rate, I put on a new filter and retuned the carb the way it was before. No bad idle problems now. This weekend I will try about four different settings for the altitude I am at, 3200 ft. Settings #5,7,a custom one, and another one that a friend from Edelbrock Corp. told me to try. I have a sniffer at my disposal so that will help at idle. I reset the air mixture screws, timing, and idle set screws today and went wheeling. The timing was set by ear and will be dialed in this weekend. I can romp it for a second, WOT, and it will not backfire. If I hold it at about 3500 for about 4 seconds it will very slightly backfire. No pinging, remember this was set by ear, will dial in this weekend. I wheeled a trail today that I had wheeled in the 4-runner. The Jeep ate it up where the 4-runner tucked tail. Biggest problem was getting the tires NOT to spin on the trail, soggy snow melt mud. I also reset the float rest position to 9/32 to check the off-road needle and seat kit. I figured that I would try a few different levels to see what each did, only takes a few minutes and I can do it while on the trail. I took it up a hill the other day that some of the quadrunners were having trouble with bogged a little but still ran. Damn I love Jeeps. I think that you are right about the tuning procedure, if you only use the settings listed in the book. I found one that works really well for my altitude that isn't in the book, but I will have to lean the secondaries out a touch. Or another setting that I will have to richen up a little. Knowing one of the guys at Edelbrock personally really helps to pick custom settings. How did things turn out with your Edelbrock?
