I took my factory 780 carb off after I bought my car to get it rebuilt because it wasn't running properly, so I bought a 750 and put it on the car for the time being. The 750 has been performing great until just resently. I can drive my car say 10 miles to our local Steak 'n Shake and it idle's at 900 each and every time I stop. When I leave to come home say an hour and a half later the car does alright for the first mile or so then the idling starts to get a little lower than 900. Before I can get half way home each time I stop I have to keep my foot on the gas pedal a little because it won't idle. The car always starts, idles, and runs great all other times with no problems. Does anyone have any idea why this could be happening and what the fix could be? Thanks, Donnie.
