Hello to all, this is what I have. I've got a 351c 2v and I need to adjust my carb and I just can't seem to get it right. I've tried to adjust 1 and 1/2 turns out on both screws. When I bought the car the left screw was tight and the drivers side screw was about to fall out. I tried to adjust it by sound and smell (no luck) I tried adjusting the timing a little to help but nothing. Now when I'm cruising at a steady speed the car jerks slightly but, constantly unless I left off the pedal or step on it. Any clues????
