Now with the rebuild it idles at 3500 cold and when attempting to move the car under it's own power, it wants to red line the rpm. I ended up having to push the car to a level spot on the drive way to set the fuel level in the bowl.
I've read the threads dealing with setting the fuel mixture screw, but my car will not kick the fans on no matter how long it's run. I replaced the thermostat in the bottom of the radiator before doing the carb rebuild and it still wouldn't start the fans. I did try to put the AFM screw back in the same number of turns it took to take out when I rebuilt the carb, but I'm unsure how appropriate that is considering it wasn't the carb that came off the car.
I tested the fans by jumpering the thermo connecter and they do run. I've replaced almost every inch of vacuum line on the engine. Approx 50 feet. I've even redone the lines in the vacuum control box located on the fire wall.
It does sound a hell of a lot healthier than it did before, but I figure the mixture has to be out of whack along with the idle. I'm not sure if I should screw with the mixture or the idle first.
When letting the engine idle (about 10 mins) it seemed to be warm but the idle never dropped down. (Cold day it melted all the frost off the hood etc) Tapping the gas pedal had no effect, it would rev up a bit then drop back down to 3 grand.
To make things more interesting, this car has had a history of strange electrical problems. In trouble shooting the interior lights, I ended up replacing the fuse box under the hood and cleared up most of the issues the car had. (interior lights, door open indicators now work etc.) Any chance I may have a problem lurking in the interior fuse box? The rear defroster seems to still have issues so I know i haven't fixed everything on the electrical front. Anyone know if a bad fuse box would contribute to the engine idle issues?
Thanks in advance
