Ok, some background infor first: 1983 CJ7 with a motorcraft 2100 and Nutter Bypass. The carb has been on for about 6 months now and has always ran great no matter what. I noticed a month ago my gas mileage going down but thought nothing of it. Last weekend I began to get problems with it flooding after the jeep was hot. If I would shut the jeep off and let it sit for 15 or 20 minutes it would smell like gas and essentially flood itself while not running. This also made for a very hard start condition as well. Again this only happened after running it and getting it hot. So I kept playing with it and testing things on the jeep.
Today the issue got progressively worse and now the jeep is flooding itself at idle. I just put new jets in so I know that it should not be flooding on idle. I have black smoke out of the exhaust and a very rough idle to say the least. The float level is correct for my setup and the jets are #48. My best guess is the power valve has gone bad and now it is letting excess fuel into the intake causing an extreme rich condition, but I wanted to run this by the people here to see what they thought. I am open to suggestions on testing the problem etc. Thanks for any help!!
Oh and I have a new power valve coming in hopefully by Friday and there are no vac leaks, gas leaks etc that I have found anywhere. That was the first thing I began looking for. My timing is also right at 9 BTC as well
