If I read what you wrote correctly you still need to check those floats. I think you tested them with the car off and that isn't the way to go. Get car running and up to temperature. Take out front site plug and set so fuel is just under hole, or takes a slight rocking to spill. Do the same with rear but that one can be a tad higher but only to the point of just about trickling out. Now go on to the 4 corner idle screws with a vacuum gauge hooked up to full vacuum. Start car and block wheels, put car in gear and adjust at rear of carb to achieve the highest steadiest vacuum per corner. After that see if you have to lower idle by adjusting idle screw. Ron
The car has a 5 speed, so it can't be in gear with the wheels blocked...
