Need help with CJ-5! (kinda long)
I have an stock 81 CJ5 that I have to CA smog on monday and I'm trying to get it running in peak condition before I do. Today, I set the idle mixture until I got the strongest vaccum and an RPM of 700. It idles SMOOTHLY (if you can believe that!), and even ran fine on the road. Spark plugs where cleaned, gapped, oil changed, ran around the block, running great. Then a couple hours later, I go to start the Jeep again. Still idles smoothly... then I begin to drive it after warmup, and it starts to bog down heavily and looses serious power and seems like it wants to die on me. I'm clueless??! any ideas what happened while it sat doing absolutely nothing? I have noticed that the carb was "sweating" gas around the gasket areas, could this be a sign of a sticking float causing fuel to spill over? I observed, and it didn't seem to be burning rich or anything like that. When looking through the carb the fuel looks like a extremely fine (invisible) mist at idle to mid accel, to very light spray (visible fuel) when heavy accel. I have the distrubutor advance hooked up to direct vaccum, should I re-route it elsewhere? I have heard this could be a problem sometimes, but it was configured this way when it was running fine. Does anybody have suggestions? I just need help with this situation, its driving me nuts.
Also, anything I could do to help get my Jeep to pass? My ECU & electrical sensors no longer work, however, it had passed before when I took it to a carb shop for adjustments (very expensive!). And since then I have upgraded my ignition to the ford TFI (should burn better, right?). I also made my own smog system to compensate for the inop-sensors. It still works the way it would have from the factory, just no longer dependant on sensors, or the stepper motor. I have heard of using a bottle of alchol and filling up with gas to help get it burning cleaner. Anybody know the validity of this "trick?"
Any help or suggestions will be greatly appreciated!!
