I just put a different motor in my car and it has been in for about a month now. While it was cold outside the car ran great. Now all of the sudden the car will not idle. I checked my floats and both were up to high so I have them just below the site plug and was able to run the car with the screw out and gas stayed in. If I turn the idle up it will stay on but as soon as I drop it down to were it needs to be the car dies. I have a holley 4 barrel carb with a edelbrock intake and a pretty good size cam if any of that matters. Thanks for any help or info.
