John/68 Barracuda & Dart
The idle on my stock `68 340 is rough and I think it`s the Carter AVS carburetor. Timing is at 16 initial and 18 mechanical w/electronic ignition. The idle mixture screw seems to work in reverse increasing rpm as you screw it in and removing the air cleaner also increases rpm. I`ve checked for vacuum leaks and haven`t found any. The car surges when driving normal too. Under WOT the car runs super. Please, any help?
